Ashok Vuyyuru dfa193fcfc msm: ipa3: Fix to avoid gsi/sys len stats mismatch
In suspend just before stopping the channel possible to receive
the IEOB interrupt and xfer pointer will not be processed in this
mode but gsi stats are updated.  In resume after starting the channel
will receive the IEOB interrupt and xfer pointer will be overwritten
because of this observing the gsi/sys len stats are not matching and
buffers won't be replinished properly leading to HW stall.
To avoid this process all data in polling context, gsi/sys len
stats are updated properly.
