reiserfs: prevent NULL pointer dereference in reiserfs_insert_item()
[ Upstream commit aacee5446a2a1aa35d0a49dab289552578657fb4 ]
The variable inode may be NULL in reiserfs_insert_item(), but there is
no check before accessing the member of inode.
Fix this by adding NULL pointer check before calling reiserfs_debug().
