patch 9.2.0022: bt_quickfix() is slow

patch 9.2.0022: bt_quickfix() is slow

Problem: In order to prevent a use-after-free, bt_quickfix() added a
call to buf_valid(), which slows it down, because Vim has to
loop through many buffers all the time (v9.0.1859)
Solution: Patch v9.0.2010 fixed a similar problem, so that the call to
buf_valid() is no longer required (zeertzjq)

fixes: #19169
closes: #19183
