misc: mic/scif: fix copy-paste error in scif_create_remote_lookup

BugLink: https://bugs.launchpad.net/bugs/1836968

commit 6484a677294aa5d08c0210f2f387ebb9be646115 upstream.

gcc '-Wunused-but-set-variable' warning:

drivers/misc/mic/scif/scif_rma.c: In function 'scif_create_remote_lookup':
drivers/misc/mic/scif/scif_rma.c:373:25: warning:
 variable 'vmalloc_num_pages' set but not used [-Wunused-but-set-variable]

'vmalloc_num_pages' should be used to determine if the address is
within the vmalloc range.
