    remove SWRITE* I/O types · 9cb569d6

    These flags aren't real I/O types, but tell ll_rw_block to always
    lock the buffer instead of giving up on a failed trylock.
    
    Instead add a new write_dirty_buffer helper that implements this semantic
    and use it from the existing SWRITE* callers.  Note that the ll_rw_block
    code had a bug where it didn't promote WRITE_SYNC_PLUG properly, which
    this patch fixes.
    
    In the ufs code clean up the helper that used to call ll_rw_block
    to mirror sync_dirty_buffer, which is the function it implements for
    compound buffers.
