vmdk: Fix comment regarding max l1_size coverage
Commit
b0651b8c246d ("vmdk: Move l1_size check into vmdk_add_extent")
extended the l1_size check from VMDK4 to VMDK3 but did not update the
default coverage in the moved comment.
The previous vmdk4 calculation:
(512 * 1024 * 1024) * 512(l2 entries) * 65536(grain) = 16PB
The added vmdk3 calculation:
(512 * 1024 * 1024) * 4096(l2 entries) * 512(grain) = 1PB
Adding the calculation of vmdk3 to the comment.
In any case, VMware does not offer virtual disks more than 2TB for
vmdk4/vmdk3 or 64TB for the new undocumented seSparse format which is
not implemented yet in qemu.
