[PATCH] btrfs-progs: replace BTRFS_NUM_MIRRORS with BTRFS_MAX_MIRRORS
The chunk-recover.c/BTRFS_NUM_MIRRORS in the userspace means
the same thing as ctree.h/BTRFS_MAX_MIRRORS in the kernelspace,
so to stay consistent with the kernelspace, just make this movement
in the userspace:
chunk-recover.c/BTRFS_NUM_MIRRORS
===>
ctree.h/BTRFS_MAX_MIRRORS
This provides convenience for future use.
