Use min_t instead of min function in qlge/qlge_main.c
Fixes following checkpatch.pl warning:
WARNING: min() should probably be min_t(int, MAX_CPUS, num_online_cpus())

Currently the pointer 'reporter' is not being initialized and is
being read in a netdev_warn message.  The pointer is not used
and is redundant, fix this by removing it and replacing the reference
to it with priv->reporter instead.

strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.

This silences the related checkpatch warnings from:
5dbdb2d87c29 ("checkpatch: prefer strscpy to strlcpy")

The debugging code in the following ifdef land
 - QL_ALL_DUMP
 - QL_REG_DUMP
 - QL_DEV_DUMP
 - QL_CB_DUMP
 - QL_IB_DUMP
 - QL_OB_DUMP

becomes unnecessary because,
 - Device status and general registers can be obtained by ethtool.
 - Coredump can be done via devlink health reporter.
 - Structure related to the hardware (struct ql_adapter) can be obtained
   by crash or drgn.

devlink health could be used to get coredump. No need to send so much
data to the kernel ring buffer.

With force_coredump module parameter set, devlink health dump will
reset the MPI RISC first which takes 5 secs to be finished.

Note that only NIC function that owns the firmware can do the
force_dumping. Otherwise devlink will receive an EPERM error.

Stop calling ql_release_all in qlge_init_device and free things one step
at a time.

struct qlge_adapter *qdev is now a private structure of struct devlink
and memset is not necessary.

Initialize devlink health dump framework for the qlge driver so the
coredump could be done via devlink.

struct qlge_adapter is now used as the private data structure of
struct devlink so it could exist independently of struct net_device
and devlink reload could be supported in the future. The private data
of PCIe driver now points to qlge_adapter.

Since devlink_alloc will zero out struct qlge_adapter, memset in
qlge_init_device is not necessary.
