[PATCH] src: Don't check for retval of g_strsplit()

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

The g_strsplit() function can return NULL if and only if either
the input string is NULL or delimiter is NULL or an empty string.
In neither of places we call it any of the conditions is true and
thus we don't need to check for the return value.
