As check_for_converted_path() detects an "already converted path",
_shadow_copy2_strip_snapshot_internal() just returns without modifying the value

By using shadow_copy2_strip_snapshot_converted() instead of

VSS object by checking the "converted" bool.

but that would be a new semantic in the module, I'll leave this excersize for
the future when we clean up the usage of shadow_copy2_strip_snapshot() in the
whole module.

This change also switches to using the absolute paths in both place where
convert_sbuf() is called.

Later in the open code called from openat_pathref_fsp() -> fd_openat() ->
non_widelink_open() since 4.14 we call SMB_VFS_FSTAT() where fsp->fsp_name will
