fs/ecryptfs: Use kmap_local_page() in ecryptfs_write()
kmap_atomic() is deprecated in favor of kmap_local_page().
Therefore, replace kmap_atomic() with kmap_local_page() in
ecryptfs_write().
kmap_atomic() is implemented like kmap_local_page() which also disables
page-faults and preemption (the latter only for !PREEMPT_RT kernels).
The code within the mapping/un-mapping in ecryptfs_write() does not
depend on the above-mentioned side effects so that a mere replacement of
the old API with the new one is all that is required (i.e., there is no
need to explicitly call pagefault_disable() and/or preempt_disable()).
Tested in a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel with
HIGHMEM64GB enabled.
