Message:

VBoxPci-linux.c: use kernel_write instead of vfs_write as of Linux 4.14.
bugref:9057: VBoxPci: vfs_write() no longer exported by Linux kernel

As of Linux 4.14 vfs_write() is no longer exported for use by modules. Other
users have been converted to use kernel_write(), which is a wrapper around
vfs_write() with some added boiler-plate calls to make it safe to use on
kernel addresses too. It seems to me like we should probably already have
been using kernel_write(), but I prefer to leave that decision to someone who
knows the code, so this change switches over for 4.14 and later.
