gru: fix cache coherency issues with instruction retry
Fix two problems related to GRU instruction failures. Cache coherency is
not maintained for CBEs except when loading or unloading contexts. When
reading a CBE to extract error information, the CBE must first be flushed
from the cache.
The function that reads kerrnel CBEs was reading the wrong CBE.
