mm/buddy: dump PG_compound_lock page flag
The array pageflag_names[] does conversion from page flags into their
corresponding names so that a meaningful representation of the
corresponding page flag can be printed. This mechanism is used while
dumping page frames. However, the array missed PG_compound_lock. So
the PG_compound_lock page flag would be printed as a digital number
instead of a meaningful string.
The patch fixes that and prints "compound_lock" for the PG_compound_lock
page flag.
