[PATCH] reiserfs: use generic_file_open for open() checks

The other common disk-based file systems (I checked ext[23], xfs, jfs)
check to ensure that opens of files > 2 GB fail unless O_LARGEFILE is
specified.  They check via generic_file_open or their own open routine.

ReiserFS doesn't have an f_op->open defined, and as such, it's possible to
open files > 2 GB without O_LARGEFILE.

This patch adds the f_op->open member to conform with the expected
behavior.
