FW credit flow control is enabled for only WMI ctrl
service(CE3) but credit update is requested unconditionally
on all HTC services as part of HTC tx in CE3/CE0/CE4.
This is causing WOW failure as FW is not expecting credit
report request on other end-points(CE0/CE4).
Request credit report only on those endpoints where
credit flow control is enabled.
Testing:
Tested on WCN3990 HW.
Tested FW: WLAN.HL.2.0-01192-QCAHLSWMTPLZ-1.
