lib/vdso: Mark do_hres_timens() and do_coarse_timens() __always_inline()
In the same spirit as commit c966533f8c6c ("lib/vdso: Mark do_hres()
and do_coarse() as __always_inline"), mark do_hres_timens() and
do_coarse_timens() __always_inline.
The measurement below in on a non timens process, ie on the fastest path.
On powerpc32, without the patch:
clock-gettime-monotonic-raw: vdso: 1155 nsec/call
clock-gettime-monotonic-coarse: vdso: 813 nsec/call
clock-gettime-monotonic: vdso: 1076 nsec/call
With the patch:
clock-gettime-monotonic-raw: vdso: 1100 nsec/call
clock-gettime-monotonic-coarse: vdso: 667 nsec/call
clock-gettime-monotonic: vdso: 1025 nsec/call
