net/mlx5: fix UAR allocation diagnostics messages

Browse Source 
Depending on kernel capabilities and rdma-core version the mapping
of UAR (User Access Region) of desired memory caching type (non-cached
or write combining) might fail. The PMD implements the flexible
strategy of UAR mapping, alternating the type of caching to succeed.
During this process the failure diagnostics messages are emitted.
These messages are merely diagnostics ones and the logging level
should be adjusted to DEBUG.
