wayland-server: Properly handle EAGAIN from wl_connection_read()

commit 3cddb3c692acd3536a7cc8542a29f0cc3c0ac3d6 casted len to an
unsigned value to compare to sizeof results.  However,
wl_connection_read() can fail, setting errno to EAGAIN and returning
a value of -1.

When cast to an unsigned type this leads to a loop condition of true
when it should be false.
