Joseph Qi de19433423 ocfs2: fix crash when mount with quota enabled 
There is a reported crash when mounting ocfs2 with quota enabled.

  RIP: 0010:ocfs2_qinfo_lock_res_init+0x44/0x50 [ocfs2]
  Call Trace:
    ocfs2_local_read_info+0xb9/0x6f0 [ocfs2]
    dquot_load_quota_sb+0x216/0x470
    dquot_load_quota_inode+0x85/0x100
    ocfs2_enable_quotas+0xa0/0x1c0 [ocfs2]

    vfs_get_tree+0x25/0xb0
    path_mount+0x465/0xac0
    __x64_sys_mount+0x103/0x140

It is caused by when initializing dqi_gqlock, the corresponding dqi_type
and dqi_sb are not properly initialized.

This issue is introduced by commit 6c85c2c728, which wants to avoid
accessing uninitialized variables in error cases.  So make global quota
info properly initialized.
