ecryptfs: fix error code for missing xattrs in lower fs
commit cfce08c6bdfb20ade979284e55001ca1f100ed51 upstream.
If the lower file system driver has extended attributes disabled,
ecryptfs' own access functions return -ENOSYS instead of -EOPNOTSUPP.
This breaks execution of programs in the ecryptfs mount, since the
kernel expects the latter error when checking for security
capabilities in xattrs.
