ANDROID: GKI: Add initialization for rwsem's oem_data and vendor_data.

Browse Source 
Add initialization for rwsem's oem_data and vendor_data.
The __init_rwsem() already contains a hook, but this function
may be called before the rwsem_init hook is registered,
causing some rwsem's oem_data to be uninitialized and
causing unpredictable errors
