crypto: caam - Implement fast-path for error codes with no handler
Implement fast-path error code printout for errors with no associated handler function. This reduces calls to this kmalloc() nonsense in SPRINTFCAT() already. Note that the format of output is compatible with the old code, even if -- exposed like this -- it looks a bit weird. Checkpatch complains on this one as well.
