[PATCH] fix reservation discarding in affs
- remove affs_put_inode, so preallocations aren't discared unnecessarily
often.
- remove affs_drop_inode, it's called with a spinlock held, so it can't
use a mutex.
- make i_opencnt atomic
- avoid direct b_count manipulations
- a few allocation failure fixes, so that these are more gracefully
handled now.
