read/write_pieced_value: Drop 'buffer_size' variable 

When the variable 'buffer_size' in read_pieced_value and
write_pieced_value was introduced, it was needed for tracking the buffer's
allocated size.  Now that the buffer's data type has been changed to a
std::vector, the variable is no longer necessary; so remove it.

gdb/ChangeLog:

	* dwarf2loc.c (read_pieced_value): Remove buffer_size variable.
	(write_pieced_value): Likewise.
