write_pieced_value: Fix copy/paste error in size calculation
In write_pieced_value, the number of bytes containing a portion of the
bit-field in a given piece is calculated with the wrong starting offset;
thus the result may be off by one. This bug was probably introduced when
copying this logic from read_pieced_value. Fix it.
gdb/ChangeLog:
* dwarf2loc.c (write_pieced_value): Fix copy/paste error in the
calculation of this_size.
