Subject: [PATCH] qcacld-3.0: Remove qdf_op_protect/unprotect for IPA RX

wlan_ipa_w2i_cb is notify cb for IPA RX terminated
scenario and therefore it is invoked on a per-packet
basis.

qdf_op_protect and qdf_op_unprotect leads to ~100mbps
througput degradation for IPA RX terminated scenario
on MDM platforms. Thus remove qdf_op_protect and
qdf_op_unprotect on MDM platforms as a temporary
workaround to unblock releases and meet KPI. Note that
this will be revisited.
