[PATCH] crypto: fix spelling errors in comments

[Sun Chaobo <suncoding913@gmail.com>]

Fix several spelling mistakes in comments across the following files:

- crypto/tea.c: Correct "algorogrthm" to "algorithm"
- crypto/lrw.c: Correct "mutliple" to "multiple"
- crypto/drbg.c: Correct "additonal" to "additional"

No functional change.
