binder: fix printk format for commands
Make sure we use unsigned format specifier %u for binder commands as
most of them are encoded above INT_MAX. This prevents negative values
when logging them as in the following case:
[ 211.895781] binder: 8668:8668 BR_REPLY 258949 0:0, cmd -2143260157 size 0-0 ptr 0000006e766a8000-0000006e766a8000
