mm/kmemleak: skip the remaining scan phases when interrupted

kmemleak_scan() scans the per-cpu sections, the struct page ranges and the
task stacks in sequence.  Each loop now bails out once scan_block()
reports the scan was interrupted, but the later phases are still entered
and only bail on their first scan_block() call.

Jump straight to the gray list scan once a phase reports an interrupted
scan, so the remaining scan phases are not entered at all.  This does not
change the scan results, it only avoids the pointless re-entry.
