    fs/fatfs: Fix open for write
    
    When fatfs_open() was called to open file
    for writing it set FA_WRITE flag to fat driver.
    It is enough if file already exists but if
    it first call to open file to write it always
    failed.
    
    Now additional flag FA_OPEN_ALWAYS is added
    to make sure file will be created if it's not
    present yet.
    
    For FS_ACCESS_READ only flag file still must
    exists before.
