[media] gspca: avoid unused variable warnings
When CONFIG_INPUT is disabled, multiple gspca backend drivers
print compile-time warnings about unused variables:
media/usb/gspca/cpia1.c: In function 'sd_stopN':
media/usb/gspca/cpia1.c:1627:13: error: unused variable 'sd' [-Werror=unused-variable]
media/usb/gspca/konica.c: In function 'sd_stopN':
media/usb/gspca/konica.c:246:13: error: unused variable 'sd' [-Werror=unused-variable]
This annotates the variables as __maybe_unused, to let the compiler
know that they are declared intentionally.

Fixes: c2f644aeeba3 ("[media] gspca_cpia1: Add support for button")
