libmsc: Map SMPP command status to GSM 04.11 cause
Send SMS RP ERROR with a failure cause that relates to the status returned by the ESME in the deliver_sm_resp. Actual mapping array is limited as most phones I tested don't seem to care about the failure cause anyway, although some will display a different notification for GSM411_RP_CAUSE_MO_NUM_UNASSIGNED Change-Id: I61fb2d9ef4f2d2eabdc49b53d9966ad328d15e51
