linker: Make linker_error set LinkStatus to false

Remove the other places that set LinkStatus to false since they all
immediately follow a call to linker_error.  The function linker_error
was previously known as linker_error_printf.  The name was changed
because it may seem surprising that a printf function will set an
error flag.
