wifi: ath11k: Fix error handling in ath11k_wmi_p2p_noa_event()
if (noa_descriptors > WMI_P2P_MAX_NOA_DESCRIPTORS), there is a mix of
return and goto. In such a case, 'td' should be freed to avoid a memory
leak.
While at it, change ath11k_wmi_p2p_noa_event() to return void.
'0' was returned in all cases, even in case of error and the only caller
does not handle the return value.
This is also more consistent with most of functions called from
ath11k_wmi_tlv_op_rx().
