 timecounter: Merge FreeBSD change r284256

 Tweaks for r284178:

 Do not include machine/atomic.h explicitely, the header is already
 included
 by sys/systm.h.

 Force inlining of tc_getgen() and tc_setgen().  The functions are used
 more than once, which causes compilers with non-aggressive inlining
 policies to generate calls.
