cluster/dht: Check if fd is opened on dst subvol
If an fd is opened on a file, the file is migrated and the cached subvol is updated in the inode_ctx before an fd based fop is sent, the fop is sent to the dst subvol on which the fd is not opened. This causes the FOP to fail with EBADF. Now, every fd based fop will check to see that the fd has been opened on the dst subvol before winding it down.
