KLD is preloaded with loader(8) and leads to infinity loops.
Also do not return EEXIST error code from MOD_LOAD handler, because
we have undocumented(?) ability replace kernel's module with preloaded one.
And if we have so, then preloaded module will be initialized first.
Thus error in MOD_LOAD handler will be triggered for the kernel.

scheme. The LDM is a logical volume manager for MS Windows NT and it
is also known as dynamic volumes. It supports about 2000 partitions
and also provides the capability for software RAID implementations.
This version implements only partitioning scheme capability and based
on the linux-ntfs project documentation and several publications across
the Web. NOTE: JBOD, RAID0 and RAID5 volumes aren't supported.
An access to the LDM metadata is read-only. When LDM is on the disk
partitioned with MBR we can also destroy metadata. For the GPT
partitioned disks destroy action is not supported.

o Creation of a Boot Camp enabled GPT is not supported.
o Automatically disable Boot Camp when the GPT has been changed so that
there's either no EFI partition or no HFS+ partition.
o The first 4 partitions (by index) get mirrored in the MBR.

Remove message about non empty bootcode, we can not break something
while GEOM_PART_EBR_COMPAT is defined.
But without GEOM_PART_EBR_COMPAT any changes in EBR are allowed and we
can accidentally wipe the boot code. To do not break anything save
the first EBR chunk and keep it untouched each time when we are
changing EBR. Note that we are still not support boot code for EBR.
