cluster/ec: Handle absence of keys in some callback dict
Problem: This issue arises when we do a rolling update
from 3.7.5 to 3.7.9.
For 4+2 volume running 3.7.5, if we update 2 nodes
and after heal completion kill 2 older nodes, this
problem can be seen. After update and killing of
bricks, 2 nodes will return inodelk count key in dict
while other 2 nodes will not have inodelk count in dict.
This is also true for get-link-count.
During dictionary match , ec_dict_compare, this will
lead to mismatch of answers and the file operation
on mount point will fail with IO error.
Solution:
Don't match inode, entry and link count keys while
comparing two dictionaries. However, while combining the
data in ec_dict_combine, go through all the dictionaries
and select the maximum values received in different dicts
for these keys.
