wifi: iwlwifi: increase number of RX buffers for EHT devices

[ Upstream commit 2cf254c1e24fa8f01f42f5a8c77617e56bf50b86 ]

EHT devices can support 512 MPDUs in an A-MPDU, each of
which might be an A-MSDU and thus further contain multiple
MSDUs, which need their own buffer each. Increase the number
of buffers to avoid running out in high-throughput scenarios.
