Log Message:
MI efiboot: Stop using efi_bootdp after exclusive open for PXE
Once boot device is exclusively opened for Simple Network Protocol,
further access via device path (efi_bootdp) is illegal.
For some implementations, boot device path gets corrupted by
exclusive open, and subsequent access by efi_device_path_depth(),
e.g., causes infinite recursion.
Fix PXE boot for QEMU/aarch64 with EDK2 on some Linux distributions.
Thanks yamaguchi@ for comments and tests.
