Disable the now unpredicably bogus check for whether we have
eneough queue space before queuing a bunch of IP fragments.

As the comment in the committed change says, in the post-if_transmit(),
post-SMP, post-preemption world, there's just too much overlapping
concurrent code paths and different approaches to driver transmit
queue management to have this code even remotely be effective.

The only specific place it could be useful is if ALTQ is enabled
but again it doesn't at all promise that all the fragments will be
transmitted anyway.

The main reason for committing this change is to disable a parallel
place where the drops counter is incremented.  This is a side effect
of an upcoming change to ixgbe/cxgbe to handle the queue drops
counter slightly better.
