crypto: inside-secure - wait for the request to complete if in the backlog
[ Upstream commit 4dc5475ae0375ea4f9283dfd9b2ddc91b20d4c4b ]
This patch updates the safexcel_hmac_init_pad() function to also wait
for completion when the digest return code is -EBUSY, as it would mean
the request is in the backlog to be processed later.
Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto engine driver")
