staging: nvec: Avoid the use of BUG_ON

Prevent a kernel panic by avoiding the use of the BUG_ON macro. Checkpatch detected this issue.

The BUG_ON macro is not needed as such cases shouldn't happen and they were introduced for debugging purposes.

---
Changes in v2:
- Remove the BUG_ON macro used in the module, as Marc Dietrich suggested.

Changes in v3:
- Include detailed commit message according to the reason of the macro removal, as Fabio Estevam suggested.

Changes in v4:
- Commit message adjustment in order to avoid the WARN_ON macro which is not used, as Julia suggested.
