Subject: [PATCH] Initialize pointer variable platform before use in
 get_num_of_asic (#12351)

- Why I did it
Pointer variable platform not initialized before use in get_num_of_asic of src/systemd-sonic-generator/systemd-sonic-generator.c. Then wild pointer will introduce undetermined exception when use in snprintf at line 545 .
Other pointers in this function like token will be assigned the value before use, and will not have such issue.

- How I did it
Initialized pointer platform to NULL when defined and before use.
