path: short-circuit git_path_apply_relative on error

Browse Source 
Short-circuit the call to `git_path_resolve_relative` in case
`git_buf_joinpath` returns an error. While this does not fix any
immediate errors, the resulting code is easier to read and handles
potential new error conditions raised by `git_buf_joinpath`.
