cluster/ec: Fix tracking of good bricks

The bitmask of good and bad bricks was kept in the context of the
corresponding inode or fd. This was problematic when an external
process (another client or the self-heal process) did heal the
bricks but no one changed the bitmaks of other clients.

This patch removes the bitmask stored in the context and calculates
which bricks are healthy after locking them and doing the initial
xattrop. After that, it's updated using the result of each fop.
