greybus: operation: print id when synchronous operation timeout
In case of a synchronous operation timeout error, it's helpful for
purpose of debugging to print the operation id in the error message, so
that we know if the response is received at a later time after operation
time out.
Testing Done:
- Observe the error message below when response comes later after
operation timeout:
[ 792.973978] greybus greybus1: 0/0:0: synchronous operation id 0x0005
of type 0x21 failed: -110
[ 800.646694] greybus greybus1: 0/0:0: unexpected response id 0x0005
received
