bus: fsl-mc: fsl-mc-allocator: Initialize mc_bus_dev before use
Fixes a clang compiler warning:
>> drivers/bus/fsl-mc/fsl-mc-allocator.c:108:12: warning: variable 'mc_bus_dev' is uninitialized when used here [-Wuninitialized]
dev_err(&mc_bus_dev->dev, "resource mismatch\n");
Fixes: b3134039c5b3 ("bus: fsl-mc: fsl-mc-allocator: Improve error reporting")
