tap: Clarify calculation of TAP_MSGS
The rationale behind the calculation of TAP_MSGS isn't necessarily obvious.
It's supposed to be the maximum number of packets that can fit in pkt_buf.
However, the calculation is wrong in several ways:
* It's based on ETH_ZLEN which isn't meaningful for virtual devices
* It always includes the qemu socket header which isn't used for pasta
* The size of pkt_buf isn't relevant for vhost-user
We've already made sure this is just a tuning parameter, not a hard limit.
Clarify what we're calculating here and why.
