smb3: allow skipping signature verification for perf sensitive configurations
Add new mount option "signloosely" which enables signing but skips the sometimes expensive signing checks in the responses (signatures are calculated and sent correctly in the SMB2/SMB3 requests even with this mount option but skipped in the responses). Although weaker for security (and also data integrity in case a packet were corrupted), this can provide enough of a performance benefit (calculating the signature to verify a packet can be expensive especially for large packets) to be useful in some cases.
