ath10k: snoc: fix unbalanced IRQ enable in crash recovery
In ath10k_snoc_hif_stop() we skip disabling the IRQs in the crash
recovery flow, but we still unconditionally call enable again in
ath10k_snoc_hif_start().
We can't check the ATH10K_FLAG_CRASH_FLUSH bit since it is cleared
before hif_start() is called, so instead check the
ATH10K_SNOC_FLAG_RECOVERY flag and skip enabling the IRQs during crash
recovery.
This fixes unbalanced IRQ enable splats that happen after recovering from
a crash.
