net/ena: limit refill threshold by fixed value

Divider used for both Tx and Rx cleanup/refill threshold can cause too
big delay in case of the really big rings - for example if the 8k Rx
ring will be used, the refill won't trigger unless 1024 threshold will
be reached. It will also cause driver to try to allocate that much
descriptors.

Limiting it by fixed value - 256 in that case, would limit maximum
time spent in repopulate function.

net/ena: rework getting number of available descriptors

ena_com API should be preferred for getting number of used/available
descriptors unless extra calculation needs to be performed.

Some helper variables were added for storing values that are later
reused. Moreover, for limiting the value of sent/received packets to
the number of available descriptors, the RTE_MIN is used instead of

net/ena: refactor Rx

* Split main Rx function into multiple ones - the body of the main
  was very big and further there were 2 nested loops, which were
  making the code hard to read
* Rework how the Rx mbuf chains are being created - Instead of having
  while loop which has conditional check if it's first segment, handle
  this segment outside the loop and if more fragments are existing,
  process them inside.
* Initialize Rx mbuf using simple function - it's the common thing for
  the 1st and next segments.
* Create structure for Rx buffer to align it with Tx path, other ENA
  drivers and to make the variable name more descriptive - on DPDK, Rx
  buffer must hold only mbuf, so initially array of mbufs was used as
  the buffers. However, it was misleading, as it was named
  "rx_buffer_info". To make it more clear, the structure holding mbuf
