[PATCH v2 3/3] powerpc/powernv/idle: Rename pnv_first_spr_loss_level variable

[Pratik Rajesh Sampat]

Replace the variable name from using "pnv_first_spr_loss_level" to
"pnv_first_fullstate_loss_level".

As pnv_first_spr_loss_level is supposed to be the earliest state that
has OPAL_PM_LOSE_FULL_CONTEXT set, however as shallow states too loose
SPR values, render an incorrect terminology.
