ocfs2: fix crash when mount with quota enabled

There is a reported crash when mounting ocfs2 with quota enabled.

RIP: 0010:ocfs2qinfolockresinit+0x44/0x50 [ocfs2] Call Trace: ocfs2localreadinfo+0xb9/0x6f0 [ocfs2] dquotloadquotasb+0x216/0x470 dquotloadquotainode+0x85/0x100 ocfs2enablequotas+0xa0/0x1c0 [ocfs2] ocfs2fillsuper.cold+0xc8/0x1bf [ocfs2] mountbdev+0x185/0x1b0 legacygettree+0x27/0x40 vfsgettree+0x25/0xb0 pathmount+0x465/0xac0 _x64sysmount+0x103/0x140

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

This issue is introduced by commit 6c85c2c72819, which wants to avoid accessing uninitialized variables in error cases. So make global quota info properly initialized.
