W1: ds2490: Increase timeout when waiting for status
commit d25221525e0e2cfd70e4ec7216549c06609a8bd2 upstream.
Adjust the bulk message timeout to the other ones (1000ms). Otherwise the
following dmesg errors can be seen on a Raspberry Pi:
[ 31.492386] Failed to read 1-wire data from 0x81: err=-110.
[ 31.504168] 0x81: count=-110, status:
