sys/common_linux.h: move the definition of a global nlmsg variable

Browse Source 
This global variable cannot be used for pseudo syscalls as they can
run concurrently (in threaded mode). It can only be used during
initialization, and if initialization routines are not enabled, nlmsg
will become an unused variable.
