fb: Initialize fb_info mutexes in framebuffer_alloc()
This way they'll be properly initialized early enough for users that may touch them before the framebuffer has been registered. Drivers that allocate their fb_info structure some other way (like matrocfb's broken static allocation) need to be fixed up appropriately.
