ligd f9d20ea4d2 sigdeliver: fix system block when kill signal to idle in SMP 
Bug description:

CONFIG_SMP=y

Suppose we have 2 cores in SMP, here is the ps return:

PID GROUP CPU PRI POLICY TYPE    NPX STATE     STACK   USED  FILLED COMMAND
  0     0   0   0 FIFO   Kthread N-- Assigned 004076 000748  18.3%  CPU0 IDLE
  1     0   1   0 FIFO   Kthread N-- Running  004096 000540  13.1%  CPU1 IDLE

nsh> kill -4 0
or:
nsh> kill -4 1

system blocked.

Reason:

In func xx_sigdeliver() restore stage, when saved_irqcount == 0, that means
rtcb NOT in critical_section before switch to xx_sigdeliver(), then we need
reset the critical_section state before swith back.

Fix:

Add condition to cover saved_irqcount == 0.
