Subject: vmxnet3: do not reschedule napi for rx processing
Patch-mainline: v6.0-rc1
Git-commit: 5b91884bf50b21d34bd3daa5c8f8b7e92e0a2c46
References: bsc#1200431

Commit '2c5a5748105a ("vmxnet3: add support for out of order rx
completion")' added support for out of order rx completion. Within
that patch, an enhancement was done to reschedule napi for processing
rx completions.

However, it can lead to missing an interrupt. So, this patch reverts
that part of the code.
