Lv Yunlong 80b2787789 firmware/efi: Fix a use after bug in efi_mem_reserve_persistent 
commit 9ceee7d0841a8f7d7644021ba7d4cc1fbc7966e3 upstream.

In the for loop in efi_mem_reserve_persistent(), prsv = rsv->next
use the unmapped rsv. Use the unmapped pages will cause segment
fault.

Fixes: 18df7577adae6 ("efi/memreserve: deal with memreserve entries in unmapped memory")
