crypto: qat - use strscpy_pad to simplify adf_service_string_to_mask

Browse source

Use strscpy_pad() to copy buf and zero-pad any trailing bytes instead of
zero-initializing the local services buffer and then using strscpy() to
copy into it. Also use the strscpy_pad() return value to detect string
truncation instead of checking the caller-provided length.

Remove the now-unused length parameters from
adf_service_string_to_mask() and adf_parse_service_string(). Also remove
the redundant strnlen() call in adf_get_service_mask(), which only
computed the removed length argument.
