[PATCH xserver 3/9] xfree86: Remove unnecessary errno save/restore in xf86ReadInput

[Keith Packard]

When this code was called from SIGIO, saving and restoring errno could
possibly have made sense in some strange environment. Now that this
will not be called from a signal handler, there is no reason to do that.
