gprs: Return 0 from gsup_client_connect if ok or retry timer enabled

Currently the gsup_client_connect return 0 if the call to
ipa_client_conn_open was successful and -errno otherwise. This makes
it difficult for the caller to determine, whether the the whole
operation has been cancelled (currently on EBADF, ENOTSOCK,
EAFNOSUPPORT, EINVAL) or whether the GSUP client will retry to
connect after a timeout. This will cause gprs_gsup_client_create to
destroy the GSUP client object, even if the error might be temporary.

This patch changes the function to return 0 if (and only if)
ipa_client_conn_open was successful or the retry timer has been
started. Since the return value 0 doesn't guarantee, that a
subsequent call to gprs_gsup_client_send will succeed, this shouldn't
break anything.
