wlan: Don't process loggerApp netlink messages during unload

As part of driver unload, HOST will nl_srv_sock to NULL and as
same is passed to kernel(netlink_unicast()) while processing
user space netlink messages from loggerApp socket, there is a
possibility NULL pointer dereference.
Hence don't process user space netlink messages from loggerApp
socket if unload is in progress.
