scsi: qla2xxx: Fix buffer overrun
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.
