Revert "protocol/client: return ENOENT if inode context is missing"

This reverts commit 4439876a34f2e5d19db0d8b05ce7d7722c1c466f.

This revert is necessary for path handle resolution to work over the
protocol where client/server talk only with the path, without inode
or parent inode and generation numbers
