Subject: [PATCH 2/4] habanalabs: use dev_dbg upon hint address failure

Hint address failure that results in a valid mapping with an address
that was allocated by the driver is not a real failure.

Therefore, the driver shouldn't notify about this in kernel log. The
user is responsible to check the returned address.
