    bitset: __BIT_FFS_AT(): Fix herald comment, take 2
    
    Remove the reference to the nonexistent 'end' parameter.  While here,
    rephrase a bit.
    
    I did the initial comment fix (commit "bitset: Fix __BIT_FFS_AT()'s
    herald comment", f3ab0d86e8070c73) as part of an experiment introducing
    macros to operate on ranges of bits in a bitset and subject to
    a predicate (a generalization of some code used in some pending
    modifications of the ULE scheduler), which was finally ditched as being
    too verbose and impractical to use.  I however then forgot to remove the
    reference to 'end'.
    
    No functional change.
