[PATCH v2] 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 "alogrithms" to "algorithms"
- crypto/lrw.c: Correct "mutliple" to "multiple"
- crypto/drbg.c: Correct "additonal" to "additional"

No functional change.

2.53.0

Changes since v1:
- Fixed multiple typos in the commit message description.
  1. Corrected the spelling of the target word "algorithms" (added missing 's').
  2. Fixed a typo in the quoted original error string (the original code had 
     "alogrithms", but I accidentally mistyped it again in the v1 log).
  Both are now accurately represented.
- The actual code diff remains unchanged from v1; the source code fixes 
  were already correct in v1.
- No functional changes.
