A recent change appears to have moved an #endif by accident:

In nvme-fc: it's possible to have connected active controllers
and as no references are taken on the LLDD, the LLDD can be
unloaded.  The controller would enter a reconnect state and as
long as the LLDD resumed within the reconnect timeout, the
controller would resume.  But if a namespace on the controller
is the root device, allowing the driver to unload can be problematic.
To reload the driver, it may require new io to the boot device,
and as it's no longer connected we get into a catch-22 that
eventually fails, and the system locks up.

Fix this issue by taking a module reference for every connected
controller (which is what the core layer did to the transport
module). Reference is cleared when the controller is removed.

Currently the lpfc driver sizes its cpu_map array based on
num_possible_cpus(). However, that can be a value that is less than the
highest cpu id bit that is set. As such, if a thread runs on a cpu with a
larger cpu id, or for_each_possible_cpu() is used, the driver could index
off the end of the array and return garbage or GPF.

The driver maintains its own internal copy of the "num_possible" cpu value
and sizes arrays by it.

Fix by setting the driver's value to the value of the last cpu id bit set
in the possible_mask - plus 1. Thus cpu_map will be sized to allow access
by any cpu id possible.
