linuxkpi: Fix an assertion in linux_free_kmem()

Browse source 
In the LinuxKPI, PAGE_MASK is the logical negation of FreeBSD's
PAGE_MASK, so the original assertion was simply incorrect.

Reported by:	trasz
Tested by:	trasz
Fixes:		6223d0b67af9 ("linuxkpi: Handle direct-mapped addresses in linux_free_kmem()")

(cherry picked from commit f88bd1174aab1aff7fea7241ab6e103e769d2d7a)
