octeon_ep_vf: Relocate counter updates before NAPI

Browse source

[ Upstream commit 2ae7d20fb2 ]

Relocate IQ/OQ IN/OUT_CNTS updates to occur before NAPI completion.
Moving the IQ/OQ counter updates before napi_complete_done ensures
1. Counter registers are updated before re-enabling interrupts.
2. Prevents a race where new packets arrive but counters aren't properly
   synchronized.
