wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start()

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start()

Preserve the error code if iwl_setup_deferred_work() fails.  The current
code returns ERR_PTR(0) (which is NULL) on this path.  I believe the
missing error code potentially leads to a use after free involving
debugfs.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
