[SCSI] libfc: check for err when recv and state is incorrect
If we've just created an interface and the an rport is
logging in we may have a request on the wire (say PRLI).
If we destroy the interface, we'll go through each rport
on the disc->rports list and set each rport's state to NONE.
Then the lport will reset the EM. The EM reset will send a
CLOSED event to the prli_resp() handler which will notice
that the state != PRLI. In this case it frees the frame
pointer, decrements the refcount and unlocks the rport.
The problem is that there isn't a frame in this case. It's
just a pointer with an embedded error code. The free causes
an Oops.
This patch moves the error checking to be before the state
checking.
