HID: roccat: add bounds checking in kone_sysfs_write_settings()

[ Upstream commit d4f98dbfe717490e771b6e701904bfcf4b4557f0 ]

This code doesn't check if "settings->startup_profile" is within bounds
and that could result in an out of bounds array access.  What the code
does do is it checks if the settings can be written to the firmware, so
it's possible that the firmware has a bounds check?  It's safer and
easier to verify when the bounds checking is done in the kernel.
