Btrfs-progs: reset chunk state if we restart check

Browse Source 
If we hid a corrupt block that we fix and we restart the fsck loop you will get
lots of noise about duplicate block groups and such.  This is because we don't
clear the block group and chunk cache when we do this restart.  This patch fixes
that, which is a little tricky since the structs are linked together with
various linked lists, but this passed with a user who was hitting this problem.
Thanks,
