can: isotp: isotp_bind(): return -EINVAL on incorrect CAN ID formatting
Commit 3ea566422cbd ("can: isotp: sanitize CAN ID checks in
isotp_bind()") checks the given CAN ID address information by
sanitizing the input values.
This check (silently) removes obsolete bits by masking the given CAN
IDs.
Derek Will suggested to give a feedback to the application programmer
when the 'sanitizing' was actually needed which means the programmer
provided CAN ID content in a wrong format (e.g. SFF CAN IDs with a CAN
ID > 0x7FF).
