cmd_nvedit.c: make error message more helpful
When calling getenv_f() with a too small buffer, it would print an
error message like this:
env_buf too small [32]
This is not really helpful as it does not give any indication which of
the calls might have failed. Change this into:
env_buf [32 bytes] too small for value of "hwconfig"
so we know at least which variable caused the overflow; this usually
allows to quickly find the related code as well.
