extras: Turn eager-lock off for gluster-block
With the current implementation of eager-lock FINODELK is taking so much
time that cassandra workload times out and errors out. AFR eager-locking
needs to be changed similar to EC eager-locking to make things work
as expected. In the interim, it is better to turn it off
This is how the profile looks if eager-lock is turned on:

81.76 209862.12 us 15.00 us 1992486.00 us 29318 FINODELK
This is how profile looks if eager-lock is turned off:
