[PATCH 1/2] gdb/dwarf: don't pass lowpc/highpc to dwarf2_ranges_read in cooked_indexer::scan_attributes

[simon.marchi@polymtl.ca]

From: Simon Marchi <simon.marchi@polymtl.ca>

It's not necessary to pass pointers to those variables
(dwarf2_ranges_read checks then for nullptr), and they are not used.
Remove them.
