mds/Locker.cc: fix warning about 'Possible null pointer dereference'

Fix following warning from cppcheck:
 [src/mds/Locker.cc:2255] -> [src/mds/Locker.cc:2258]: (error)
   Possible null pointer dereference: in - otherwise it is redundant
   to check it against null.

Since head_in used for call pick_inode_snap() is already valid,
there is no need to check if 'CInode *in' is not NULL. Remove
not needed check.
