GFS2: Fix uninitialized VFS inode in gfs2_create_inode
When gfs2_create_inode() fails due to quota violation, the VFS
inode is not completely uninitialized. This can cause a list
corruption error.
This patch correctly uninitializes the VFS inode when a quota
violation occurs in the gfs2_create_inode codepath.
Resolves: rhbz#1059808
