Series [net] ch_ktls: Remove the checks for u_ctx pointer | expand

Commit Message

The u_ctx pointer in case of ch_ktls will always be valid. As u_ctx is
ch_ktls ctx pointer and remains valid until driver is running.

So removing the u_ctx checks.

Fixes: 65e302a9bd57 ("cxgb4/ch_ktls: Clear resources when pf4 device is removed")
