From: Jiri Kosina <jkosina@xxxxxxx>
klp_mutex is shared between core.c and transition.c, and as such would
rather be properly located in livepatch.h so that we don't have to play
'extern' games from .c sources.
This also silences sparse warning (wrongly) suggesting that klp_mutex
should be defined static.
