Josh Poimboeuf 9ac50f7311 context_tracking: Always inline ct_{nmi,irq}_{enter,exit}() ...

Thanks to CONFIG_DEBUG_SECTION_MISMATCH, empty functions can be
generated out of line.  These can be called from noinstr code, so make
sure they're always inlined.

Fixes the following warnings:

  vmlinux.o: warning: objtool: irqentry_nmi_enter+0xa2: call to ct_nmi_enter() leaves .noinstr.text section
  vmlinux.o: warning: objtool: irqentry_nmi_exit+0x16: call to ct_nmi_exit() leaves .noinstr.text section
  vmlinux.o: warning: objtool: irqentry_exit+0x78: call to ct_irq_exit() leaves .noinstr.text section

Fixes: 6f0e6c1598 ("context_tracking: Take IRQ eqs entrypoints over RCU")
