crypto: ccp: use scoped_with_init_fs() for SEV file access
Replace the manual init_task root retrieval with scoped_with_init_fs()
to temporarily override current->fs. This allows using the simpler
filp_open() instead of the init_root() + file_open_root() pattern.
open_file_as_root() ← sev_read_init_ex_file() / sev_write_init_ex_file()
← sev_platform_init() ← __sev_guest_init() ← KVM ioctl — user process context
Needs init's root because the SEV init_ex file path should resolve
against the real root, not a KVM user's chroot.
