[hmac] Remove Invalid Assertion

As `prim_packer` is updated, one of the assertion inside sha2_pad is no
longer valid assumption.

packer now sends out the data first when `flush_i` request is received.
Then it asserts the `flush_done_o` one cycle later. That signal is used
has `hash_process` in the SHA engine. So that the `hash_process_flag`
can be delayed 2 cycles.
