eCryptfs: Use generic_file_splice_read()
eCryptfs is currently just passing through splice reads to the lower
filesystem. This is obviously incorrect behavior; the decrypted data is
what needs to be read, not the lower encrypted data. I cannot think of any
good reason for eCryptfs to implement splice_read, so this patch points the
eCryptfs fops splice_read to use generic_file_splice_read.
