libogc: mutex_t isn't declared in usbstorage.h

[dontwantanick]

I know it's maybe not really a bug, but the type mutex_t which is declared in ogc/mutex.h is used in ogc/usbstorage.h, but it's not inside any of its includes.

If you want to use ogc/usbstorage.h, you have to inculde ogc/mutex.h too. This doesn't make sense to me.
