nouveau: reset the bo resource bus info after an eviction

Browse Source 
[ Upstream commit f35c9af45ea7a4b1115b193d84858b14d13517fc ]

Later attempts to refault the bo won't happen and the whole
GPU does to lunch. I think Christian's refactoring of this
code out to the driver broke this not very well tested path.
