rcu: Make RCU IRQ enter/exit functions rely on in_nmi()entry-v4-part1

The rcu_nmi_enter_common() and rcu_nmi_exit_common() functions take an
"irq" parameter that indicates whether these functions are invoked from
an irq handler (irq==true) or an NMI handler (irq==false).  However,
recent changes have applied notrace to a few critical functions such
that rcu_nmi_enter_common() and rcu_nmi_exit_common() many now rely
on in_nmi().  Note that in_nmi() works no differently than before,
but rather that tracing is now prohibited in code regions where in_nmi()
would incorrectly report NMI state.

Therefore remove the "irq" parameter and inlines rcu_nmi_enter_common() and
rcu_nmi_exit_common() into rcu_nmi_enter() and rcu_nmi_exit(),
respectively.
