Rather than #define-ing common code function calls to OS-dependent
ones, make the osdep versions match the common code expectations,
adjust the FreeBSD specific code to use those, and remove the
#defines.
In the FreeBSD specific code, use "i40e_mem_reserved" for the
now expected but unused argument to i40e_allocate_dma_mem().

Using pointer from the cdev directly is dangerous since we have no reference
on it, and it may change any time. That caused panic if device has gone.
While there, report capacity change only if it really changed.

This is primarily only of interest to ZFS developers, but it makes it

double-free mbufs.
Like ixgbe(4) chipsets, EOP is only set on the final descriptor
in a chain of descriptors. So, to free the whole list of descriptors,
we should free the current slot _and_ the assembled list of descriptors
that make up the fragment list.
The existing code was setting discard once it saw EOP + an error status;
it then freed all the subsequent descriptors until the next EOP. That's
totally the wrong order.
- Do not ever set a counter to a value. For those counters
that we don't increment, but return directly from hardware
create cases in if_get_counter() method.

If bpobj_space() returned non-zero here, the sublist would have been
left open, along with the bonus buffer hold it requires. This call
does not invoke any calls to bpobj_close() itself.
This bug doesn't have any known vector, but was found on inspection.
