mm: compaction: early termination in compact_nodes()
No need to continue try compact memory if pending fatal signal, allow loop
termination earlier in compact_nodes().
The existing fatal_signal_pending() check does make compact_zone()
break out of the while loop, but it still enters the next zone/next
nid, and some unnecessary functions(eg, lru_add_drain) are called.
There was no observable benefit from the new test, it is just found
from code inspection when refactoring compact_node().
