perf/x86/intel/lbr: Mark the {rd,wr}lbr_{to,from} wrappers __always_inline
The {rd,wr}lbr_{to,from} wrappers are invoked in hot paths, e.g. context
switch and NMI handler. They should be always inline to achieve better
performance. However, the CONFIG_OPTIMIZE_INLINING allows the compiler
to uninline functions marked 'inline'.
Mark the {rd,wr}lbr_{to,from} wrappers as __always_inline to force
inline the wrappers.
