Fix error codes for missing storage pools

The storage pool driver is mistakenly using the error code
VIR_ERR_INVALID_STORAGE_POOL which is for diagnosing invalid
pointers. This patch switches it to use VIR_ERR_NO_STORAGE_POOL
which is the correct code for cases where the storage pool does
not exist

* src/storage/storage_driver.c: Replace VIR_ERR_INVALID_STORAGE_POOL
  with VIR_ERR_NO_STORAGE_POOL
