Subject: [PATCH] Docs/mm: fix typos and grammar in page_tables.rst

Correct several spelling and grammatical errors in the page tables
documentation. This includes:
- Fixing "a address" to "an address"
- Fixing "pfs" to "pfns"
- Correcting the possessive "Torvald's" to "Torvalds'"
- Fixing "instruction that want" to "instruction that wants"
- Fixing "code path" to "code paths"
