udf: kill useless file header comments for vfs method implementations

There's not need to document vfs method invocation rules, we have
Documentation/filesystems/vfs.txt and Documentation/filesystems/Locking
for that.  Also a lot of these comments where either plain wrong or
horrible out of date.

-/*
- * udf_lookup
- *
- * PURPOSE
- *      Look-up the inode for a given name.
- *
- * DESCRIPTION
- *      Required - lookup_dentry() will return -ENOTDIR if this routine is not
- *      available for a directory. The filesystem is useless if this routine is
- *      not available for at least the filesystem's root directory.
- *
- *      This routine is passed an incomplete dentry - it must be completed by
- *      calling d_add(dentry, inode). If the name does not exist, then the
- *      specified inode must be set to null. An error should only be returned
- *      when the lookup fails for a reason other than the name not existing.
- *      Note that the directory inode semaphore is held during the call.
- *
- *      Refer to lookup_dentry() in fs/namei.c
- *      lookup_dentry() -> lookup() -> real_lookup() -> .
- *
- * PRE-CONDITIONS
- *      dir                     Pointer to inode of parent directory.
- *      dentry                  Pointer to dentry to complete.
- *      nd                      Pointer to lookup nameidata
- *
- * POST-CONDITIONS
- *      <return>                Zero on success.
- *
- * HISTORY
- *      July 1, 1997 - Andrew E. Mileski
- *      Written, tested, and released.
