Subject: [PATCH] mm/vmalloc: add 'align' parameter explanation for pvm_determine_end_from_reverse

Kernel-doc markup has a issue on pvm_determine_end_from_reverse:
mm/vmalloc.c:3145: warning: Function parameter or member 'align' not
described in 'pvm_determine_end_from_reverse'
Add a explanation for it to remove the warning.
