If devm_spi_register_master() fails in meson_spicc_probe(),
spicc->core is left undisabled. The patch fixes that.

Found by Linux Driver Verification project (linuxtesting.org).

Neil Armstrong 454fa271bc spi: Add Meson SPICC driver
The SPICC hardware block on the Amlogic SoCs is Communication oriented and
can do Full-Duplex 8- to 32-bit width SPI transfers up to 30MHz.

The current driver only supportd the PIO transfer mode since the DMA seems
broken on available hardware.
