Most probably you have some mix of your patched code, this part is not upstream at all, the only occurrence is here https://github.com/espruino/Espruino/blob/25648d5fc9c586e7a3271e944e5e3b3fb9bfd74b/targets/nrf5x/jshardware.c#L2458 and it allows to recover when some other code pulls CS high but that 'other code' is not there at all. This part is also not lcd_spi_unbuf specific, it is a minimal fix that allows sharing same spi with flash and anything else (like accelerometer on DK08)
here https://gist.github.com/fanoush/627200137d8199c993d6c54901c1c819 is patch with @jeffmer 's changes of
lcd_spi_unbufthat worked for me, all that is not in upstream Espruino
