qla2x00t-32gbit: Serialize fc_port alloc in N2N

Browse Source 
For N2N, fc_port struct is created during report id acquisition.  At
later time, the loop resync (fabric, n2n, loop) would trigger the rest
of the login using the created fc_port struct.  The loop resync logic
can trigger another fc_port allocation if the 1st allocation was not
able to execute.  This patch prevents the 2nd allocation trigger.
