[PATCH] ocfs2: remove unnecessary NULL check in ocfs2_grab_folios()

[Dan Carpenter <dan.carpenter@linaro.org>]

Smatch complains that checking "folios" for NULL doesn't make sense
because it has already been dereferenced at this point.  Really passing a
NULL "folios" pointer to ocfs2_grab_folios() doesn't make sense, and
fortunately none of the callers do that.  Delete the unnecessary NULL
check.
