iio: core: check return value when calling dev_set_name()
I got a null-ptr-deref report when doing fault injection test:
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: 0010:strlen+0x0/0x20
Call Trace:
start_creating+0x199/0x2f0

__iio_device_register+0x4da/0x1b40 [industrialio]

spi_probe+0x183/0x210
really_probe+0x285/0xc30
If dev_set_name() fails, the dev_name() is null, check the return
value of dev_set_name() to avoid the null-ptr-deref.
