Subject: [PATCH] Fix clang 15 warning in cxgbe

Clang 15 warns:

    sys/dev/cxgbe/cudbg/cudbg_lib.c:2949:6: error: variable 'i' set but not used [-Werror,-Wunused-but-set-variable]
            int i = 0;
                ^

Apparently 'i' was meant as the current retry counter, but '1' was used
in the while loop comparison instead, making the loop potentially
infinite, if 'busy' never gets reset.
