[PATCH 05/14] fscrypt: don't clear flags on crypto transform

[Eric Biggers]

From: Eric Biggers <ebiggers at google.com>

fscrypt is clearing the flags on the crypto_skcipher it allocates for
each inode.  But, this is unnecessary and may cause problems in the
future because it will even clear flags that are meant to be internal to
the crypto API, e.g. CRYPTO_TFM_NEED_KEY.

Remove the unnecessary flag clearing.
