Pascal Mazon ec12df9504 net/tap: fix support for large Rx queues
Rx queues configured with more than 1023 descriptors cause readv() calls to
fail due to more iovec entries than permitted by the kernel. As a result,
no packets can be received.

Quietly limit internal Rx queue size to the maximum number of iovec entries
to fix this issue.

Fixes: 0781f5762cfe ("net/tap: support segmented mbufs")
