ieee802154: ca8210: Add missing check for kfifo_alloc() in ca8210_probe()

Browse Source 
[ Upstream commit 2c87309ea7 ]

ca8210_test_interface_init() returns the result of kfifo_alloc(),
which can be non-zero in case of an error. The caller, ca8210_probe(),
should check the return value and do error-handling if it fails.
