patch 9.1.1253: abort when closing window with attached quickfix data
Problem: If win_close() is called with a window that has quickfix stack
attached to it, the corresponding quickfix buffer will be
closed and freed after the buffer was already closed. At that
time curwin->w_buffer points to NULL, which the CHECK_CURBUF
will catch and abort if ABORT_ON_ERROR is defined
Solution: in wipe_qf_buffer() temporarily point curwin->w_buffer back to
curbuf, the window will be closed anyhow, so it shouldn't
matter that curbuf->b_nwindows isn't incremented.
