Subject: [PATCH v2] net: ipv4: fix spelling typos in comments

Correct spelling typos in several code comments.

- alignement -> alignment
- wont -> won't
- orignal -> original
- substract -> subtract
- Segement -> Segment
- splitted -> split

Signed-off-by: Shi Hao <i.shihao.999@...il.com>

changes v2:
- Update subject message
- Add additional spelling typo fixes
- Combined all typo fixes into single patch as requested
