Remove adjust_bind_mount_path call 

If user configured target is used, path should be used as the absolute
path within the dump target direct, and user should be fully aware of
the path structure within the target device. The adjust_bind_mount_path
call here make it very hard to control the behavior.

Especially, if it's a cross device bind mount, this will likely create a
invalid path in the target. And for atomic case, adjust_bind_mount_path call
here assumes user will always pass root device as the explicitly configured
dump target, which is not true.

If user configured target device is used, the path is always be the
absolute path inside of given target. If user don't know about the path
structure in the target device, then user should either use the path
based config, or carefully exam the target device before using it as a
dump target.
