Colin Ian King aed9eb1b21 ext4: fix null pointer dereference on sbi ...

In the case of a kzalloc failure when allocating sbi we end up
with a null pointer dereference on sbi when assigning sbi->s_daxdev.
Fix this by moving the assignment of sbi->s_daxdev to after the
null pointer check of sbi.

Detected by CoverityScan CID#1455379 ("Dereference before null check")

Fixes: 5e405595e5 ("ext4: perform dax_device lookup at mount")
