Borislav Petkov bfaeafcfc2 usbserial: fix inconsistent lock state
In commit acd2a847e7 usb_serial_generic_write()
disables interrupts when taking &port->lock which is also taken in
usb_serial_generic_read_bulk_callback() resulting in an inconsistent lock state
due to the latter not disabling interrupts on the local cpu. Fix that by
disabling interrupts in the latter call site also.
