[PATCH] usb/serial/generic: Fix compile error

[Javier Martinez Canillas <martinez.javier@gmail.com>]

usb/serial/generic.c gives me a compile error when CONFIG_MAGIC_SYSRQ is
not defined.

The problem is that usb_serial_handle_sysrq_char() calls handle_sysrq()
that only is defined if CONFIG_MAGIC_SYSRQ is defined.

This patch add an empty handle_sysrq inline function if
CONFIG_MAGIC_SYSRQ is not defined and generic.c compiles cleanly.
