    msdosfs: fix bug in msfdosfs_hashins().
    This function returns an error if there is already a denode in the hash table:
    EBUSY if the hashed denode represents a live file and EINVAL if it represents a
    deleted but still opened file.
    There was a typo in the function causing it to check for liveness in the denode
    to insert instead of the already inserted one.  As a consequence, if N threads
    were in a race in deget() to insert a new denode for the same file in the hash
    table, the losers would fail with EINVAL instead of retrying.
