mlxsw: core_linecards: Fix double memory deallocation in case of invalid INI file
In case of invalid INI file mlxsw_linecard_types_init() deallocates memory
but doesn't reset pointer to NULL and returns 0. In case of any error
occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init()
calls mlxsw_linecard_types_fini() which performs memory deallocation again.
Add pointer reset to NULL.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
