Fix unused variable warning in mlx5_ib_devx.c

Browse Source 
With clang 15, the following -Werror warning is produced:

    sys/dev/mthca/mthca_cmd.c:662:23: error: variable 'tc' set but not used [-Werror,-Wunused-but-set-variable]
            int ts __unused = 0, tc = 0;
                                 ^

The 'ts' and 'tc' variables are eventually used only in mthca_dbg()
macros, if CONFIG_INFINIBAND_MTHCA_DEBUG is defined. Ensure 'ts' and
'tc' are only declared and used when CONFIG_INFINIBAND_MTHCA_DEBUG is
defined.
