The ipa3_get_hw_type_index() uses the ipa3_ctx->ipa_config_is_mhi
for MHI flavor detection. Therefore the ipa3_ctx->ipa_config_is_mhi
has to be initialized before the ipa3_get_hw_type_index() call.

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.
