Eric Biggers d3d5e69b5e fscrypt: use ENOTDIR when setting encryption policy on nondirectory 
[ Upstream commit dffd0cfa06d4ed83bb3ae8eb067989ceec5d18e1 ]

As part of an effort to clean up fscrypt-related error codes, make
FS_IOC_SET_ENCRYPTION_POLICY fail with ENOTDIR when the file descriptor
does not refer to a directory.  This is more descriptive than EINVAL,
which was ambiguous with some of the other error cases.

I am not aware of any users who might be relying on the previous error
code of EINVAL, which was never documented anywhere, and in some buggy
kernels did not exist at all as the S_ISDIR() check was missing.

This failure case will be exercised by an xfstest.
