features/bitrot: do not remove the quarantine handle in forget
If an object is marked as bad, then an entry is corresponding to the bad object is created in the .glusterfs/quarantine directory to help scrub status. The entry name is the gfid of the corrupted object. The quarantine handle is removed in below 2 cases. 1) When protocol/server revceives the -ve lookup on an entry whose inode is there in the inode table (it can happen when the corrupted object is deleted directly from the backend for recovery purpose) it sends a forget on the inode and bit-rot-stub removes the quarantine handle in upon getting the forget. refer to the below commit f853ed9c61bf65cb39f859470a8ffe8973818868: 2) When bit-rot-stub itself realizes that lookup on a corrupted object has failed with ENOENT. But with step1, there is a problem when the bit-rot-stub receives forget due to lru limit exceeding in the inode table. In such cases, though the corrupted object is not deleted (either from the mount point or from the backend), the handle in the quarantine directory is removed and that object is not shown in the bad objects list in the scrub status command. So it is better to follow only 2nd step (i.e. bit-rot-stub removing the handle from the quarantine directory in -ve lookups). Also the handle has to be removed when a corrupted object is unlinked from the mount point itself.
