[gdb/symtab] Fix data race on per_objfile->sym_cu
We have both:
...
gdb/dwarf2/read.c:9590: internal-error: read_file_scope: \
Assertion `per_objfile->sym_cu == nullptr' failed.
...
and a data race between:
...
#0 read_file_scope gdb/dwarf2/read.c:9590 (gdb+0x83c8ca)
#1 process_die gdb/dwarf2/read.c:8614 (gdb+0x839dc1)
#2 process_full_comp_unit gdb/dwarf2/read.c:8383 (gdb+0x839400)
#3 process_queue_item gdb/dwarf2/read.c:7592 (gdb+0x83591f)
...
and:
