scsi: iscsi: qla4xxx: fix double free in probe 

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: afaf5a2d34 ("[SCSI] Initial Commit of qla4xxx")
