From: Quinn Tran <qutran@xxxxxxxxxxx> commit b68710a8094fdffe8dd4f7a82c82649f479bb453 upstream. Klocwork warning: Buffer Overflow - Array Index Out of Bounds Driver uses fc_els_flogi to calculate size of buffer. The actual buffer is nested inside of fc_els_flogi which is smaller. Replace structure name to allow proper size calculation.
