Commit Message

Currently we are checking file mode after getxattr call.
Due to this the return value would be 0, which would change the getxattr return value.
As xattr_size will be 0, nfs4_getfacl will fail with error EINVAL.
This patch fixes this issue by moving the file mode check before
getxattr call.
