Austin Christ 6862e6ad95 efi/capsule: Allocate whole capsule into virtual memory ...

According to UEFI 2.6 section 7.5.3, the capsule should be in contiguous
virtual memory and firmware may consume the capsule immediately. To
correctly implement this functionality, the kernel driver needs to vmap
the entire capsule at the time it is made available to firmware.

The virtual allocation of the capsule update has been changed from kmap,
which was only allocating the first page of the update, to vmap, and
allocates the entire data payload.
