Make fb_modesetting_disabled() a static-inline function when it is
defined in the header file. Avoid the linker error shown below.

 ld: drivers/video/fbdev/core/fbmon.o: in function `fb_modesetting_disabled':
 fbmon.c:(.text+0x1e4): multiple definition of `fb_modesetting_disabled'; drivers/video/fbdev/core/fbmem.o:fbmem.c:(.text+0x1bac): first defined here

A bug report is at [1].
