USB: serial: mos7840: remove set but not used variables 'number, serial'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/usb/serial/mos7840.c: In function 'mos7840_send_cmd_write_baud_rate':
drivers/usb/serial/mos7840.c:1584:16: warning:
variable 'number' set but not used [-Wunused-but-set-variable]
drivers/usb/serial/mos7840.c: In function 'mos7840_change_port_settings':
drivers/usb/serial/mos7840.c:1695:21: warning:
variable 'serial' set but not used [-Wunused-but-set-variable]
'number' never used since introduction in commit 3f5429746d91 ("USB: Moschip
7840 USB-Serial Driver")
'serial' not used since commit 5833041f1b13 ("USB: serial: remove unnecessary
reinitialisations of urb->dev")
