The NULL pointer check for superset->muxnames will always evaluate
true since muxnames is an array within struct omap_mux. Remove the
superfluous check to avoid warnings when using LLVM/clang.

For the reference, the warning generated by LLVM/clang:
arch/arm/mach-omap2/mux.c:1056:18: warning: address of array
'superset->muxnames' will always evaluate to 'true' [-Wpointer-bool-conversion]
                if (!superset->muxnames || !superset->muxnames[0]) {
                    ~~~~~~~~~~~^~~~~~~~
