The ath11k_dbring_bufs_replenish() and ath11k_dbring_fill_bufs()
take a "gfp" parameter but they since they take spinlocks, the
allocations they do have to be atomic. This causes a bug because
ath11k_dbring_buf_setup passes GFP_KERNEL for the gfp flags.
The fix is to use GFP_ATOMIC and remove the unused parameters.
