Colin Ian King bfc6b1cabc mm/swapfile.c: make pointer swap_avail_heads static ...

The pointer swap_avail_heads is local to the source and does not need to
be in global scope, so make it static.

Cleans up sparse warning:

  mm/swapfile.c:88:19: warning: symbol 'swap_avail_heads' was not declared. Should it be static?
