Unless smbdirect_connection_legacy_debug_proc_show()
wants to debug-log keep_alive_interval as microseconds,
a magnitude higher precision than available by the way,
keepalive_interval_msec should not be multiplied by 1000.

Fix smbdirect_map_sges_from_iter() to use pre-decrement, not post-decrement
so that it cleans up the correct slots.

ib_dma_map_sg() modifies the provided scatterlist and returns the
number of mapped entries, which can be fewer than the requested
mr->sgt.nents if the DMA controller coalesces contiguous memory
segments. Passing the original, uncoalesced count to ib_map_mr_sg()
causes memory registration failures if coalescing actually occurs.
Capture the actual mapped count returned by ib_dma_map_sg() and pass it
to ib_map_mr_sg() to ensure correct MR registration.
Also update the ib_dma_map_sg() error logging to drop the error
pointer formatting, since the return value is an integer count
rather than an error code.
Ensure a proper error code (-EIO) is assigned when DMA mapping or
MR registration fails.

This makes it easier to rebuild cifs.ko and ksmbd.ko against
a running kernel.

This is a better solution than
EXPORT_SYMBOL_FOR_MODULES(__sym, "cifs,ksmbd") as it makes
it possible to rebuild smbdirect.ko against a
running kernel and then load the existing cifs.ko and ksmbd.ko
from the running kernel.
