net/bnxt: improve error recovery information messages

The error recovery async event messages are often mistaken
for errors. Improved the wording to clarify the meaning of
these events.
Also, take the first step towards more inclusive language.
The references to master will be changed to primary.
For example: "bnxt_is_master_func" will be renamed to
"bnxt_is_primary_func()".
