- Avoid potentially leaving one boot where BOOTSERVICE_ACCESS variable
can be written by OS
- Remove incorrect implication that OpenCore's NVRAM reset will clear
static4 settings
Normally only useful for our HttpBootDxe, which supports HTTP
boot from static IP address as long as URI is also pre-specified.
The NVRAM setting should affect normal EDK II derived network stacks
and will configure a static IP on the card, but this will later be
ignored and overridden by DHCP when PXE or HTTP boot is started in the
standard network stack.
