Subject: [PATCH] mm: Fix two typos in comments for to_vmem_altmap()

Commit 4b94ffdc4163 ("x86, mm: introduce vmem_altmap to augment
vmemmap_populate()"), introduced the to_vmem_altmap() function.

The comments in this function contain two typos (one misspelling
of the Kconfig option CONFIG_SPARSEMEM_VMEMMAP, and one missing
letter 'n'), let's fix them up.
