Eric van Gyzen 8310609fdd db_search_symbol: prevent pollution from bogus symbols
The kernel will never map the first page, so any symbols in that
range cannot refer to addresses.  Some third-party assembly files
define internal constants which appear in their symbol table.
Avoiding the lookup for those symbols avoids replacing small offsets
with those symbols during disassembly.
