[PATCH 3/5] ppc: spapr: assert early rather late in h_enter_nested()

[Harsh Prateek Bora]

Currently, it asserts very late in the code flow if lpid is already initialized.
Ideally, it should assert in the beginning if that is the case. This patch
brings assert check in the beginning alongwith the related initialization.
