This particular test case was previously written with the assumption 
that moving an already suspended VS to suspend state will not return any 
exception from the provider and is a valid state transition. But this is 
not true anymore. Also, the the above test case used to XFAIL sometime 
back because of the problem in RequestedStateChange() bug.
The provider now returns an exception when we try to suspend the VS 
which is already in suspended state. The exception is checked in the 
try_request_state_change() library function.
The part of the code in the loop which we execute is not suppose to 
return any exception. Hence the code in the loop and the one in 
try_request_state_change() cannot be combined together.
Regarding validating the req_state value after 
try_request_state_change() can be done to make sure the state still 
remains the same as it was in before calling the RequestStateChange().
