feature/bitrot: Fix recovery of corrupted hardlink
Problem: When a file with hardlink is corrupted in ec volume, the recovery steps mentioned was not working. Only name and metadata was healing but not the data. Cause: The bad file marker in the inode context is not removed. Hence when self heal tries to open the file for data healing, it fails with EIO. Background: The bitrot deletes inode context during forget. Briefly, the recovery steps involves following steps. 1. Delete the entry marked with bad file xattr from backend. Delete all the hardlinks including .glusters hardlink as well. 2. Access the each hardlink of the file including original from the mount. The step 2 will send lookup to the brick where the files are deleted from backend and returns with ENOENT. On ENOENT, server xlator forgets the inode if there are no dentries associated with it. But in case hardlinks, the forget won't be called as dentries (other hardlink files) are associated with the inode. Hence bitrot stube won't delete it's context failing the data self heal. Fix: Bitrot-stub should delete the inode context on getting ENOENT during lookup.
