NFS: Convert kmap_atomic() to kmap_local_folio()
kmap_atomic() is deprecated in favor of kmap_local_{folio,page}().
Therefore, replace kmap_atomic() with kmap_local_folio() in
nfs_readdir_folio_array_append().
kmap_atomic() disables page-faults and preemption (the latter only for
!PREEMPT_RT kernels), However, the code within the mapping/un-mapping in
nfs_readdir_folio_array_append() does not depend on the above-mentioned
side effects.
Therefore, a mere replacement of the old API with the new one is all that
is required (i.e., there is no need to explicitly add any calls to
pagefault_disable() and/or preempt_disable()).
Tested with (x)fstests in a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel
with HIGHMEM64GB enabled.
