Jacob Erlbeck d6267d12d8 sgsn: Add SGSN_ERROR_CAUSE_NONE and use it instead of 0
Currently an error_cause of 0 is being used to indicate normal
operation. Albeit this is not a defined GMM cause, the value is not
explicitly reserved.

This commit adds the macro SGSN_ERROR_CAUSE_NONE and uses it for
initialisation (instead of relying on talloc_zero) and comparisons.
The value is set to -1 to be on the safe side. The VTY code is
updated to set the error_cause when using the
'update-subscriber imsi IMSI update-location-result CAUSE' command.
