[U-Boot] [PATCH 1/3] fw_env: fix type of len

This variable is assigned by a size_t, and is printed that way, but is incorrectly declared as an int. Which means we get warnings: fw_env.c: In function 'fw_setenv': fw_env.c:409:5: warning: format '%zu' expects argument of type 'size_t', but argument 3 has type 'int' [-Wformat]
