net: mvneta: Fix an out of bounds check

[ Upstream commit cdd97383 ]

In an earlier commit, I added a bounds check to prevent an out of bounds
read and a WARN().  On further discussion and consideration that check
was probably too aggressive.  Instead of returning -EINVAL, a better fix
would be to just prevent the out of bounds read but continue the process.

Background: The value of "pp->rxq_def" is a number between 0-7 by default,
or even higher depending on the value of "rxq_number", which is a module
parameter. If the value is more than the number of available CPUs then
it will trigger the WARN() in cpu_max_bits_warn().

Fixes: e8b4fc13
