vfs/xattr: mm/shmem: kernfs: release simple xattr entry in a right way
After commit fdc85222d58e ("kernfs: kvmalloc xattr value instead of
kmalloc"), simple xattr entry is allocated with kvmalloc() instead of
kmalloc(), so we should release it with kvfree() instead of kfree().
Fixes: fdc85222d58e ("kernfs: kvmalloc xattr value instead of kmalloc")
