There were two functions who were calling "sizeof" twice.

The first one, dw2_get_real_path from gdb/dwarf2read.c, was actually
making use of OBSTACK_CALLOC which already calls "sizeof" for its third
argument.

The second, download_tracepoint_1 from gdb/gdbserver/tracepoint.c, was
explicitly calling "sizeof" inside another "sizeof".

This patch fixed both functions.
