[PATCH trivial] init: Fix comment typo in do_mounts_initrd.c

[Beibei Yang <13738176232@163.com>]

From: root <root@192.168.220.227>

The original comment incorrectly used "cwd" (current working directory)
when referring to the root change operation. The correct term should be
"pwd" (present working directory) as per process context semantics.

This is a pure comment correction with no functional impact.
