f2fs: fix an endian conversion bug detected by sparse

This patch should fix the following bug reported by kbuild test robot.

fs/f2fs/recovery.c:233:33: sparse: incorrect type in assignment
(different base types)

parse warnings: (new ones prefixed by >>)

>> recovery.c:233: sparse: incorrect type in assignment (different base types)
   recovery.c:233:    expected unsigned int [unsigned] [assigned] ofs_in_node
   recovery.c:233:    got restricted __le16 [assigned] [usertype] ofs_in_node
>> recovery.c:238: sparse: incorrect type in assignment (different base types)
   recovery.c:238:    expected unsigned int [unsigned] ofs_in_node
   recovery.c:238:    got restricted __le16 [assigned] [usertype] ofs_in_node
