Subject: [PATCH 1/2] iwlwifi: fix DVM build regression in 5.12-rc

There is no iwl_so_trans_cfg if CONFIG_IWLDVM but not CONFIG_IWLMVM:
move the CONFIG_IWLMVM guard up before the problematic SnJ workaround
to fix the build breakage.

Fixes: 930be4e76f26 ("iwlwifi: add support for SnJ with Jf devices")

Subject: [PATCH 2/2] iwlwifi: fix DVM boot regression in 5.12-rc

No time_point op has been provided for DVM: check for NULL before
calling, to fix the oops (blank screen booting non-modular kernel).

Fixes: d01293154c0a ("iwlwifi: dbg: add op_mode callback for collecting debug data.")

See "iwlwifi: pcie: fix iwl_so_trans_cfg link error when CONFIG_IWLMVM
is disabled" in [1].

Thanks for looking out that and the other one, Sedat: I swear I checked
linux-next before sending, but my check seems to have been... defective.
