Subject: [PATCH][btrfs-next] Btrfs: extent map selftest: fix non-ANSI btrfs_test_extent_map declaration

From: Colin Ian King <colin.king@...onical.com>

The function btrfs_test_extent_map requires a void argument to be ANSI C
compliant and so it matches the prototype in fs/btrfs/tests/btrfs-tests.h

Cleans up sparse warning:
fs/btrfs/tests/extent-map-tests.c:346:27: warning: non-ANSI function
declaration of function 'btrfs_test_extent_map'
