scsi: qla2xxx: Fix duplicate switch database entries

Browse source

commit 732ee9a912 upstream.

The response data buffer used in switch scan is reused 4 times.  (For example,
for commands GPN_FT, GNN_FT for FCP and FC-NVME) Before driver reuses this
buffer, clear it to prevent duplicate entries in our database.
