Subject: [PATCH] misc: mic: dead code removal and minor cleanup

This removes the below test in drivers/misc/mic/card/mic_virtio.c:

if (!retry) {
...
}

This is dead code because the "retry" variable was set to 100
earlier in the same function.

This also removes dev_dbg statements to print the value of this variable.
That's not interesting to print the value of a variable which value is
always the same.
