block: allow creation of fixed vhdx images
When trying to create a fixed vhd image qemu-img will return the
following error:
qemu-img: test.vhdx: Could not create image: Cannot allocate memory
This happens because of a incorrect check in vhdx.c. Specifficaly,
in vhdx_create_bat(), after allocating memory for the BAT entry,
there is a check to determine if the allocation was unsuccsessful.
The error comes from the fact that it checks if s->bat isn't NULL,
which is true in case of succsessful allocation, and exits with
error ENOMEM.
