IB/ipath: Make send buffers available for kernel if not allocated to user
A fixed partitioning of send buffers is determined at driver load time
for user processes and kernel use. Since send buffers are a scarce
resource, it makes sense to allow the kernel to use the buffers if they
are not in use by a user process.
Also, eliminate code duplication for ipath_force_pio_avail_update().
