ocfs2: fix possible uninitialized variable access
In ocfs2_local_alloc_find_clear_bits and ocfs2_get_dentry, variable numfound and set may be uninitialized and then used in tracepoint. In ocfs2_xattr_block_get and ocfs2_delete_xattr_in_bucket, variable block_off and xv may be uninitialized and then used in the following logic due to unchecked return value. This patch fixes these possible issues.
