[patch gold] Fix link error when building optimized

[Cary Coutant <ccoutant at google dot com>]

This patch fixes a link error when building dwp with optimization
turned on. The inline function check_buffer, defined in the
dwarf_reader.cc, is called from an function defined inline in the
class body. I refactored it to keep the error path, which needs
visibility into class Relobj, in dwarf_reader.cc, with the fast path
still inlined.

Tested on x86_64 with optimization turned on. OK to commit?
