cmd_nand: fix crashing bug in nand read/write

Commit 418396e212b59bf907dbccad997ff50f7eb61b16 introduced a
bug that causes nand read and nand write to crash in strcmp
due to a null pointer.

Root cause is that strchr(cmd, '.') returns a null pointer when
the input string does not contain a '.'

The strcmp function does not check for null pointers, resulting
in a crash.
