net: rmnet_ctrl_usb: Block file close until tx URBs are transmitted
Rmnet control driver is directly killing tx URBs submitted to HSIC
HW if userspace closes the file. When a file is close, all pending
data needs to get flushed. Hence wait for the pending tx URBs to
finish transfer with a timeout before file close. This will complete
all the pending transfers gracefully on tx path so that mdm device
does not miss any control channel information upon file close.
