net/bnxt: set checksum flags in vector Rx

Browse Source 
Fixed to return the checksum status of rx packets by setting
"ol_flags" correctly in vector mode receive.

These changes have been there for non vector mode receive.
In vector mode receive also indicate inner and outer checksum
errors individually in "ol_flag" to indicate L3 and L4 error.

Fixes: bc4a000f2f ("net/bnxt: implement SSE vector mode")
