Masayuki Ishikawa e277ac7a7f sched: task: Fix a potential bug in nxtask_assign_pid() ...

Summary:
- During reviewing sched_lock() in nxtask_assign_pid(),
  I noticed that g_pidhash is not protected by a critical section
- Because g_pidhash is accessed in an interrupt context,
  it should be protected by a critical section.
- Actually, nxsched_foreach(), nxsched_get_tcb() and so on
  use a critical section.

Impact:
- No impact

Testing:
- Tested with spresense:wifi (non-SMP) and spresense:wifi_smp
