The driver was printing out a lot of information upon failure, which
does not have to be interested for the user.
Changing logging level required to rebuild driver with proper flags. The
proper sysctl was added, so the level now can be changed dynamically
using bitmask.
Levels of printouts were adjusted to keep on mind end user instead of
debugging purposes.
More verbose messages were added to align the driver with the Linux.
Fix building error introduced by the r325506 by casting csum_flags to
uint64_t.

The previous way of checking for DF was not valid.
When DF is enabled, the DF bit should be 1.
The original way of checking it was wrong in 2 ways: first of all, it
was not checking for single bit, secondly, it was checking for 0.

The drbr_free() must be locked just in case code will change in the

flushed in the ena_down() call, and the lock is required only when there

Summary:
Existing code recognizes the mcp7941x RTC, but this RTC has an
enable bit at the same location as the "Clock Halt" bit on the ds1307, with an
opposite assertion (set == on, whereas CH set == clock stopped). Thus the
current code halts the clock, with no way to enable it.

* Use malloc and free explicitely, instead of ENA_MEM_FREE and ENA_MEM_FREE (the

* Always check for NULL after calling malloc (few checks were missing)
* Rework naming of the goto tags in ena_attach() for consistency
* Fix error handling in ena_attach() - few goto instructions were leading to the
wrong tag
* Destroy MMIO req read request if attach failed
