linux-user: Pass CPUArchState to target_restore_altstack

Browse source 
In most cases we were already passing get_sp_from_cpustate
directly to the function.  In other cases, we were passing
a local variable which already contained the same value.
In the rest of the cases, we were passing the stack pointer
out of env directly.
