Kyle Farnung f51e4b3b55 wifi: ath11k: clear shared SRNG pointer state on restart ... LMAC rings reuse the shared rdp/wrp pointer buffers without going through the normal SRNG hw-init path that zeros non-LMAC ring pointers. After restart, ath11k_hal_srng_clear() can therefore hand stale hp/tp state from the previous firmware instance back to the new one. Clear the shared pointer buffers while keeping the allocations in place so restart still avoids reallocating SRNG DMA memory, but starts with fresh ring-pointer state.
