Subject: [PATCH] iwlwifi: pcie: gen2: fix locking when "HW not ready"
Git-commit: 4c29c1e27a1e178a219b3877d055e6dd643bdfda
References: git-fixes
Patch-mainline: v5.17-rc5

If we run into this error path, we shouldn't unlock the mutex
since it's not locked since. Fix this in the gen2 code as well.

Fixes: eda50cde58de ("iwlwifi: pcie: add context information support")
