prima: Reduce excessive console logging while BSS transition

Currently in between authentication response and re-association
request process, driver is using unnecessary error log level
instead of debug message at many APIs and its leading to
excessive console logging. This causes roaming to take more
than 100ms since info logs are logged on the console.

Reduce the log level to avoid excessive console logging in
order to fast BSS transition.
