Subject: [PATCH] Return early when SSH config file cannot be opened

When attempting to import SSH configurations, the code previously continued
execution even when the config file could not be opened. This could lead
to undefined behavior or crashes when trying to read from an invalid file
handle.

The fix adds an early return statement when file opening fails, ensuring
proper error handling and preventing potential issues downstream.

(cherry picked from commit 70452321ceb1165f4626f53148fed12841692a50)
