linux-user: Move target_to_host_errno_table[] setup out of ioctl loop
The code to initialise the target_to_host_errno_table[] array was accidentally inside the loop through checking and initialising all the supported ioctls. This was harmless but meant that we reinitialised the array several hundred times on startup. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
