The skcipher could have been of the async variant which may return from
skcipher_encrypt() with -EINPROGRESS after having queued the request.
The FILS AEAD implementation here does not have code for dealing with
that possibility, so allocate a sync cipher explicitly to avoid
potential issues with hardware accelerators.

This is based on the patch sent out by Ard.

Incorrect num_elem parameter value (1 vs. 5) was used in the
aes_siv_encrypt() call. This resulted in only the first one of the five
AAD vectors to SIV getting included in calculation. This does not
protect all the contents correctly and would not interoperate with a
standard compliant implementation.

Fix this by using the correct number. A matching fix is needed in the AP
side (hostapd) to get FILS authentication working properly.
