NAND: Fix warning due to missing env_ptr casts to u_char * in env_nand.c.

The writeenv() and readenv() calls introduced by the recently added bad block
management for environment variables were missing casts therefore producing
compile time warnings.
While at it fixing some typo in a comment and indentation.
