x86/timer: Don't inline __const_udelay
__const_udelay is marked inline, and LTO will happily inline it everywhere
Dropping the inline saves ~44k text in a LTO build.

13954764 1736768 1499136 17190668 1064f0c vmlinux-wo-udelay-inline
Inlining it has no advantage in general, so its the right thing to do.
