crypto: x86/aesni - Align the address before aes_set_key_common()

aes_set_key_common() performs runtime alignment to the void *raw_ctx
pointer. This facilitates consistent access to the 16byte-aligned
address during key extension.

However, the alignment is already handlded in the GCM-related setkey
functions before invoking the common function. Consequently, the
alignment in the common function is unnecessary for those functions.

To establish a consistent approach throughout the glue code, remove
the aes_ctx() call from its current location. Instead, place it at
each call site where the runtime alignment is currently absent.
