ASoC: SOF: Core: Add remove_late() to sof_init_environment failure path

[ckborah]

In cases where the sof driver is unable to find the firmware and/or topology file [1], it exits without releasing the i915 runtime pm wakeref [2]. This results in dmesg warnings[3] during suspend/resume or driver unbind. Add remove_late() to the failure path of sof_init_environment so that i915 wakeref is released appropriately
