wifi: iwlwifi: move TXQ bytecount limit to queue code
This really isn't correct to be in the opmode, do the clamping
(and power-of-2 fixup that may be necessary due to this, or even
otherwise) in the queue code. Also move down the retrying of the
allocation, it should be after all the size fixups, but also it
just makes sense, and avoids retrying same-size allocations in
the case of the BZ-family A-step workaround.
