[PATCH v1] smp: Fix up and expand the smp_call_function_many() kerneldoc

["Rafael J. Wysocki" <rafael@kernel.org>]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The smp_call_function_many() kerneldoc comment got out of sync with the
function definition (bool parameter "wait" is incorrectly described as a
bitmask in it), so fix it up by copying the "wait" description from the
smp_call_function() kerneldoc and add information regarding the handling
of the local CPU to it.

Fixes: 49b3bd213a9f ("smp: Fix all kernel-doc warnings")
