When checking specific attribute from a bit mask, need to use bitwise
AND and not logical AND, fixed that.
Fixes: 145d9c541032 ('IB/core: Display extended counter set if
available')

Hi Matan,
The first patch is a true bug fix while the next two add the feature to
RoCE mode. Based upon the code patches, the RoCE code should work fine
for 4.5 without the new support, there isn't a bug there (they simply
won't respond to the ext counters port request). So I took the first
patch for-rc and the next two I'll put in for-next.
