V4L/DVB (10933): zoran: Pass zoran_fh pointers instead of file pointers

Many functions had a struct file pointer argument, but all they wants is
the struct zoran_fh pointer from the file's private data.  Since every
caller of those functions already has the zoran_fh, just pass the that
instead.  This saves a dereference in each function change.

While I'm at it, change the code formatting of affected functions to be
kernel standard style.
