It's failed to read the register, so that's likely to imply a wiring issue with the SPI data, clock, or chip select line. It's got nowhere near trying to do anything with an interrupt at that point.
Check ALL your wiring.
GPIOs 9, 10, and 11 (pins 21, 19, and 23) for MISO, MOSI, and SCLK respectively, GPIO 8 (pin 24) for chip select, your interrupt on GPIO 22 (pin 15), and a ground.
