client: account for mixed quotas in statfs

In statfs, when the quota root for a dir is discovered,
it uses that dir to base values for max_files and max_bytes.

This can be an issue when a dir is found with only one of two potential quota
fields. Take for instance, a dir with only max_files set and parent dir
has only max_bytes set. During a statfs call, it will then use the max_files
value for provided dir, but does not have a value for max_bytes. In this case,
this behavior will cause the size of the filesystem to be displayed.

Instead, find the quota root for max_files and max_bytes separately. This will
allow for mixed quotas to inherit missing values from its parent. In the above
example, max_files from current dir and max_bytes from parent dir will be
displayed.
