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.
