staging: greybus: spilib: fix use-after-free after deregistration
commit 770b03c2ca4aa44d226cf248f86aa23e546147d0 upstream.
Remove erroneous spi_master_put() after controller deregistration which
would access the already freed spi controller.
Note that spi_unregister_master() drops our only controller reference.
Fixes: ba3e67001b42 ("greybus: SPI: convert to a gpbridge driver")
