Sam Protsenko aa51579f9a cmd: fastboot: Validate user input 
In case when user provides '-' as USB controller index, like this:

    => fastboot -

data abort occurs in strcmp() function in do_fastboot(), here:

    if (!strcmp(argv[1], "udp"))

(tested on BeagleBone Black).

That's because argv[1] is NULL when user types in the '-', and null
pointer dereference occurs in strcmp() (which is ok according to C
standard specification). So we must validate user input to prevent such
behavior.

While at it, check also the result of strtoul() function and handle
error cases properly.
