btrfs-progs: fix max mirror number error for chunk-recover
When run chunk-recover on a health btrfs(data profile raid0, with plenty of data), the program has a chance to abort on the number of mirrors of an extent. According to the kernel code, the max mirror number of an extent is 3 not 2: ctree.h: BTRFS_MAX_MIRRORS 3 chunk-recover.c : BTRFS_NUM_MIRRORS 2 just change BTRFS_NUM_MIRRORS to 3, and everything goes well.
