pagemap.h: fix warning about possibly used before init var
Commit f56f821feb7b ("mm: extend prefault helpers to fault in more than
PAGE_SIZE") added in the new functions: fault_in_multipages_writeable()
and fault_in_multipages_readable().
However, we currently see:
include/linux/pagemap.h:492: warning: 'ret' may be used uninitialized in this function
include/linux/pagemap.h:492: note: 'ret' was declared here
Unlike a lot of gcc nags, this one appears somewhat legit. i.e. passing
in an invalid negative value of "size" does make it look like all the
conditionals in there would be bypassed and the uninitialized value would
be returned.
