[SCSI] qla4xxx: Fix memory corruption issue in qla4xxx_ep_connect.
In qla4xxx_ep_connect(), qla_ep->dst_addr and dst_addr are type
struct sockaddr. We are copying sizeof(struct sockaddr_in6) bytes
from dst_addr to qla_ep->dst_addr which is 12 bytes larger. This
will cause memory corruption. So we change qla_ep->dst_addr to
struct sockaddr_storage which is of 128 byte, large enough to
hold sizeof(struct sockaddr_in6).
