Cyrill Gorcunov 5372e3910c mount: btrfs -- Introduce phys_stat_resolve_dev helper (v2) 
This routine is aimed to find a mount point on which
the path passed as argument is laying on. We walk over
all mount points and see which one is matching.

Once found (in worst case it will be a root mount point
so function is never failing) we're checking if this is
btrfs and then return subvolume0 device id.

See commit 921cf873f3
for details what the hell we're doing here.

v2: rewrite mount_resolve_path w/o recursion
