[PATCH net] ice: Re-organizes reqstd/avail {R,T}XQ check/code for efficiency+readability

[Salil Mehta <salil.mehta@huawei.com>]

If user has explicitly requested the number of {R,T}XQs, then it is unnecessary
to get the count of already available {R,T}XQs from the PF avail_{r,t}xqs
bitmap. This value will get overriden by user specified value in any case.

This patch does minor re-organization of the code for improving the flow and
readabiltiy. This scope of improvement was found during the review of the ICE
driver code.

FYI, I could not test this change due to unavailability of the hardware. It
would helpful if somebody can test this and provide Tested-by Tag. Many thanks!
