Junxiao Bi 9277f8334f ocfs2: fix value of OCFS2_INVALID_SLOT
In the ocfs2 disk layout, slot number is 16 bits, but in ocfs2
implementation, slot number is 32 bits.  Usually this will not cause any
issue, because slot number is converted from u16 to u32, but
OCFS2_INVALID_SLOT was defined as -1, when an invalid slot number from
disk was obtained, its value was (u16)-1, and it was converted to u32.
Then the following checking in get_local_system_inode will be always
skipped:

 static struct inode **get_local_system_inode(struct ocfs2_super *osb,
                                               int type,
                                               u32 slot)
 {
 	BUG_ON(slot == OCFS2_INVALID_SLOT);
	...
 }
