zhenwei pi a90520da3c Distinguish command timeout ...

Distinguish command timeout from outqueue or waitqueue. For example,
A command sequence:  ...NOP,READ,WRITE...

NOP OUT command has no dependence on backend media, it is expected to
response soon. Once NOP timeout in libiscsi:
a, the command is already sent to target, the target side does *not*
   response.
b, the command is still pending in libiscsi.

Separate the two cases for trouble shooting.
