Correct a sanity check in vnode_pager_generic_putpages(). The cast used
to implement the sanity check should have been changed when we converted
the implementation of vm_pindex_t from 32 to 64 bits. (Thus, RELENG_4 is
not affected.) The consequence of this error would be a legimate write to
an extremely large file being treated as an errant attempt to write meta-
data.
