[LU-3867] filename_is_volatile() uses strtoul(..., ..., 0) to parse MDT index

Description

If llapi_create_volatile_idx() is passed an MDT index other than -1 then it uses '%.4X' to encode the index into the volatile file name. But it uses an index of 0 rather than the one provided.

filename_is_volatile() uses strtoul(..., ..., 0) to parse the MDT index out of the volatile file name.

So llapi_create_volatile_idx() ignores MDT index when specified and filename_is_volatile() doesn't properly understand MDT indices greater than 9.

Bobbie has a fix for this in gerrit already. Could you oversee that it completes testing and reviews.

Thanks
