Fix potential NULL pointer dereference of device physical path
In scsi_dev_advinfo(), if the physical path is being stored and there is a
malloc failure (malloc(9) is called with M_NOWAIT), we could wind up in a
situation where the device's physpath_len is set to the length the user
provided, but the physpath itself is NULL.
If another context then comes in to fetch the physical path value, we would
wind up trying to memcpy a NULL pointer into the caller's buffer.
So, set the physpath_len to 0 when we free the physpath on entry into the
store case for the physical path. Reset the length to a non-zero value only
after we've successfully malloced a buffer to hold it.

ipsec: Use the same keysize values for HMAC as prior to r324017
The HMAC construction natively permits any key size between 0 and the input

output length, which was used by ipsec for key sizes. (Non-ipsec consumers
need the ability to use other keysizes, hence, r324017.)
The ipsec SADB code blindly uses the auth_hash 'keysize' member for both
minimum and maximum key size, which is wrong (from an HMAC perspective).
For now, just switch it to 'hashsize', which matches the existing
expectations.
Instead it should probably use the range [0, keysize]. But there may be
other broken code in ipsec that rejects hashes with too small a minimum
key size.
