reiserfs: don't wank with EFBIG before calling do_sync_write()

look for file_capable() in there...

-   generic_file_write() is only appropriate for filesystems that are not seeking to optimize performance and want
-   something simple that works.  It is not for serious use by general purpose filesystems, excepting the one that it was
-   written for (ext2/3).  This is for several reasons:
-
-   * It has no understanding of any filesystem specific optimizations.
-
-   * It enters the filesystem repeatedly for each page that is written.
-
-   * It depends on reiserfs_get_block() function which if implemented by reiserfs performs costly search_by_key
-   * operation for each page it is supplied with. By contrast reiserfs_file_write() feeds as much as possible at a time
-   * to reiserfs which allows for fewer tree traversals.
-
-   * Each indirect pointer insertion takes a lot of cpu, because it involves memory moves inside of blocks.
-
-   * Asking the block allocation code for blocks one at a time is slightly less efficient.
-
-   All of these reasons for not using only generic file write were understood back when reiserfs was first miscoded to
-   use it, but we were in a hurry to make code freeze, and so it couldn't be revised then.  This new code should make
-   things right finally.
-
-   Future Features: providing search_by_key with hints.
