ext4: use fscrypt_prepare_new_inode() and fscrypt_set_context()
Convert ext4 to use the new functions fscrypt_prepare_new_inode() and
fscrypt_set_context(). This avoids calling
fscrypt_get_encryption_info() from within a transaction, which can
deadlock because fscrypt_get_encryption_info() isn't GFP_NOFS-safe.
For more details about this problem, see the earlier patch
"fscrypt: add fscrypt_prepare_new_inode() and fscrypt_set_context()".
