sfc: Add GFP flags to efx_nic_alloc_buffer() and make most callers allow blocking
Most call sites for efx_nic_alloc_buffer() are part of the probe or
reconfiguration paths and can allocate with GFP_KERNEL. A few others
should use GFP_NOIO (I think). Only one is in atomic context and
must use the current GFP_ATOMIC.
