NFS4: Cleanup FATTR4_WORD0_FS_LOCATIONS after decoding success
Commit 1ca843a2d2 "nfs: Fix GETATTR bitmap verification" has check
the bitmap after decoding success, but decode_attr_fs_locations forgets
cleanup the FATTR4_WORD0_FS_LOCATIONS bits.
decode_getfattr_attrs always return -EIO when meeting FS_LOCATIONS now.
