nodemask: Switch from inline to __always_inline

'inline' keyword is only a recommendation for compiler. If it decides to
not inline nodemask functions, the whole small_const_nbits() machinery
doesn't work.

This is how a standard GCC 11.3.0 does for my x86_64 build now. This patch
replaces 'inline' directive with unconditional '__always_inline' to make
sure that there's always a chance for compile-time optimization. It doesn't
change size of kernel image, according to bloat-o-meter.
