[PATCH 1/5] PM: runtime: Only queue an idle check for RPM-linked suppliers (part 2)

[Brian Norris]

Commit be5755f023e7 ("PM: runtime: Only queue an idle check for
RPM-linked suppliers") was incomplete. There are two other cases where
we perform idle checks on non-DL_FLAG_PM_RUNTIME suppliers -- in
pm_runtime_set_suspended(), and in cases were we failed to resume
suppliers.

Fixes: 5244f5e2d801 ("PM: runtime: Defer suspending suppliers")
