Josef Bacik 2018ef1d9a btrfs: use the original mount's mount options for the legacy reconfigure 
btrfs/330, which tests our old trick to allow

mount -o ro,subvol=/x /dev/sda1 /foo
mount -o rw,subvol=/y /dev/sda1 /bar

fails on the block group tree.  This is because we aren't preserving the
mount options for what is essentially a remount, and thus we're ending
up without the FREE_SPACE_TREE mount option, which triggers our free
space tree delete codepath.  This isn't possible with the block group
tree and thus it falls over.

Fix this by making sure we copy the existing mount options for the
existing fs mount over in this case.

Fixes: f044b31867 ("btrfs: handle the ro->rw transition for mounting different subvolumes")
