    rc: bluetooth: startup improvements
    
    During startup hccontrol reset needs to be run multiple times
    for iwbt to work more reliably.  Add a loop trying up to
    three times.
    
    Tested by:      various (original version; I changed test to -eq)
    Differential Revision: https://reviews.freebsd.org/D44861
    
    Fix a redirect of stderr to stdout which is going to /dev/null.
    A '&' got missing in the original rewrite from the review that
    I took and committed.  Seems no one had noticed during testing
    or review.  People may have ended up with a "/1" file in their
    root file system.
