set cyg_serial_line_status_t.stat to zero when overrun detected

If an overrun is detected, serial_indicate_status() is called with a pointer to
a cyg_serial_line_status_t structure, the 'which' item of this structure is set
to 'CYGNUM_SERIAL_STATUS_OVERRUNERR', but the 'stat' item is left
uninitialized. The proposed patch forces the 'stat' item to zero since the
generic serial driver sets 'stat' to 1 for overrun: using different values
helps distinguish the origin of the overrun problem.
