MAP: Fix reply code for UpdateInbox function

From MAP 1.1 specification, section 5.9:
"If MSE does not allow the polling of its mailbox it shall answer
with a "Not Implemented" error response."

This was affecting TC_MSE_MMB_BV_16_I qualification test case.

 HFP: Fix missing OK for AT+CLCC in virtual call

When AT+CLCC is received from HF while we're in virtual call mode there
is only non-zero index call sent without final zero index call. This
makes AT command response incomplete since no OK is sent.

From HFP specification, section 4.31.1:
"The AG shall always send OK response to HF."
