If CREATE was successful but SMB2_OP_SET_REPARSE failed then remove the
intermediate object created by CREATE. Otherwise empty object stay on the
server when reparse call failed.

This ensures that if the creating of special files is unsupported by the
server then no empty file stay on the server as a result of unsupported
operation.
