kdb: fix memory leak in kdb_setenv() when environment is full
When kdb_setenv() fails to find a free slot in __env[], the function
returns KDB_ENVFULL without freeing the previously allocated string
buffer 'ep', leaking memory on every failed call.
Add the missing kfree(ep) before returning KDB_ENVFULL.
Fixes: a30d4ff8193e ("kdb: remove usage of static environment buffer")
