Ajit Kumar Pandey 4bf5bc44ea ASoC: SOF: Fix NULL pointer exception in sof_pci_probe callback 
[ Upstream commit c61711c1c9 ]

We are accessing "desc->ops" in sof_pci_probe without checking "desc"
pointer. This results in NULL pointer exception if pci_id->driver_data
i.e desc pointer isn't defined in sof device probe:

BUG: kernel NULL pointer dereference, address: 0000000000000060
PGD 0 P4D 0
Oops: 0000 [#1] PREEMPT SMP NOPTI
RIP: 0010:sof_pci_probe+0x1e/0x17f [snd_sof_pci]
Code: Unable to access opcode bytes at RIP 0xffffffffc043dff4.
RSP: 0018:ffffac4b03b9b8d8 EFLAGS: 00010246

Add NULL pointer check for sof_dev_desc pointer to avoid such exception.
