usb: gadget: mass_storage: set msg_registered after msg registered
commit 8e55d30322c6a0ef746c256a1beda9c73ecb27a6 upstream.
If there is no UDC available, the msg register will fail and this
flag will not be set, but the driver is already added into pending
driver list, then the module removal modprobe -r can not remove
the driver from the pending list.
