Hector Palacios 8a4484bbd6 recovery: check variable returned by uboot_getenv() is not NULL 
The use of this function, which is a wrapper over libuboot_get_env(),
requires checking if the returned string is NULL.
Manipulations of such string without checking whether it's NULL may lead
to segfault errors.
This was seen during firmware update on a device that didn't have the
'dualboot' variable set.
