wlan: Acquire rtnl lock while unregistering SAP ioctls.

As part of ioctl unregister, HOST will set wireless_handlers
to NULL. This may lead to NULL pointer dereference if kernel
is processing any IOCTL simultaneously.
Hence, acquire rtnl_lock while making wireless_handlers to NULL,
as same lock is acquired while processing ioctl.
