dm: get rid of GFP_NOIO workarounds for __vmalloc and kvmalloc
In the past, the function __vmalloc didn't respect the GFP flags - it allocated memory with the provided gfp flags, but it allocated page tables with GFP_KERNEL. This was fixed in commit 451769eb ("mm/vmalloc: alloc GFP_NO{FS,IO} for vmalloc") so the memalloc_noio_{save,restore} workaround is no longer needed. The function kvmalloc didn't like flags different from GFP_KERNEL. This was fixed in commit a421ef30 ("mm: allow !GFP_KERNEL allocations for kvmalloc"), so kvmalloc can now be called with GFP_NOIO.
