Thomas Gleixner eb366989aa dm/verity_fec: Use GFP aware reed solomon init ...

Allocations from the rs_pool can invoke init_rs() from the mempool
allocation callback. This is problematic in fec_alloc_bufs() which invokes
mempool_alloc() with GFP_NOIO to prevent a swap deadlock because init_rs()
uses GFP_KERNEL allocations.

Switch it to init_rs_gfp() and invoke it with the gfp_t flags which are
handed in from the allocator.

Note: This is not a problem today because the rs control struct is shared
between the instances and its created when the mempool is initialized. But
the upcoming changes which switch to a rs_control struct per instance to
embed decoder buffers will trigger the swap vs. GFP_KERNEL issue.
