fs: add ksys_unlink() wrapper; remove in-kernel calls to sys_unlink()
Using this wrapper allows us to avoid the in-kernel calls to the sys_unlink() syscall. The ksys_ prefix denotes that this function is meant s a drop-in replacement for the syscall. In particular, it uses the same calling convention as sys_unlink(). In the near future, all callers of ksys_unlink() should be converted to call do_unlinkat() directly or, at least, to operate on regular kernel pointers. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
