reiserfs: Replace 1-element array with C99 style flex-array
UBSAN found the following issue:
================================================================================
UBSAN: array-index-out-of-bounds in fs/reiserfs/journal.c:4166:22
index 1 is out of range for type '__le32 [1]'
This is because struct reiserfs_journal_desc uses 1-element array for
dynamically sized array member, j_realblock.
This patch fixes this issue by replacing the 1-element array member with C99
style flex-array. This patch also fixes the same issue in struct
reiserfs_journal_commit as the same manner.
Fixes: f466c6fdb3b1 ("move private bits of reiserfs_fs.h to fs/reiserfs/reiserfs.h")
