cluster/afr: Disable delayed post op when eager-lock is off
Problem: When eager-lock is disabled, inodelks for write-fops on same fd conflict with each other. If eager-lock is disabled but delayed post-op is enabled then each write fop's inodelk unlock waits for post-op-delay-secs. So the conflicting write fop acquires inodelk after post-op-delay-secs. This results in post-op-delay-secs delay for every write fop on the fd for sequential writes (Ex: dd). Fix: Disable delayed-post-op when eager-lock is off.
