selftests/lsm: Fix memory leak in attr_lsm_count

Browse source

The calloc-allocated buffer in attr_lsm_count() is never released on
any exit path, including both the normal return path and the early
return when read_sysfs_lsms fails, resulting in a heap memory leak.

Add free() for the buffer on all return branches to fix the leak.
