ENA logs are adjusted to display the full ENA representation to
distinct each ENA device in case of multiple interfaces.
Using netdev_err/warn and dev_info functions for logging provides
uniform printing with clear distinction of the device and interface.
This patch changes all printing in ena_com files to use netev_* logging
functions except for messages of info level. Log functions of that level
would be printed with dev_info because of the early stage they are
called in when net_device struct isn't yet registered.
To allow using netdev_* functions in all ena_com functions, a pointer to
the net_device was added to ena_com_dev struct.
The patch also adds some log messages to make driver debugging easier.

Introduce ena_increase_stat() function to increase statistics by a
certain number.
The function includes the
- lock aquire (on 32bit machines)
- stat increase
- lock release (on 32bit machines)
line sequence that is ubiquitous across the driver.
The function increases a single stat at a time and several stats which
are increased together weren't put into a function to avoid
calling the function several times for each stat which looks bad and
might decrease performance.
