mips: unhide uasm_in_compat_space_p() declaration

uasm_in_compat_space_p() has a conditional declaration but is defined
unconditionally because of another local user, which causes a warning:

arch/mips/mm/uasm.c:421:5: error: no previous prototype for 'uasm_in_compat_space_p' [-Werror=missing-prototypes]

Make the declaration unconditional to avoid this.
