linux-user: Fix unlock_user() call in return from poll()
Correct the broken attempt to calculate the third argument
to unlock_user() in the code path which unlocked the pollfd
array on return from poll() and ppoll() emulation. (This
only caused a problem if unlock_user() wasn't a no-op, eg
if DEBUG_REMAP is defined.)
