[ Upstream commit fee92f25777789d73e1936b91472e9c4644457c8 ]
On this error path we call qla4xxx_mem_free() and then the caller also
calls qla4xxx_free_adapter() which calls qla4xxx_mem_free(). It leads to a
couple double frees:
drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->chap_dma_pool' double freed
drivers/scsi/qla4xxx/ql4_os.c:8856 qla4xxx_probe_adapter() warn: 'ha->fw_ddb_dma_pool' double freed
Fixes: afaf5a2d341d ("[SCSI] Initial Commit of qla4xxx")
