block: remove __bdevname
There is no good reason for __bdevname to exist. Just open code
printing the string in the callers. For three of them the format
string can be trivially merged into existing printk statements,
and in init/do_mounts.c we can at least do the scnprintf once at
the start of the function, and unconditional of CONFIG_BLOCK to
make the output for tiny configfs a little more helpful.
