drm/i915/guc: Keep GuC interrupts enabled when using GuC

Browse Source 
The GuC log contains a separate space used for crash dump.
We even get a separate notification for it. While we're not handling
crash differently yet, it makes sense to decouple the two right now to
simplify the following patches.

v2: Move guc_log_flush_irq_disable up to avoid movement in following
    patches (Sagar).
v3: s/guc_log_flush_irq_*/guc_flush_log_msg_*, rebase after mass rename
