media: mceusb: set timeout to at least timeout provided

Browse Source 
commit 20b794ddce upstream.

By rounding down, the actual timeout can be lower than requested. As a
result, long spaces just below the requested timeout can be incorrectly
reported as timeout and truncated.

Fixes: 877f1a7cee ("media: rc: mceusb: allow the timeout to be configurable")
