The following commit will change the return value of dev_add_param()
from -ENOSYS to NULL if CONFIG_PARAMETER is disabled. After that,
building without CONFIG_PARAMETER will return a NULL pointer to
__nvvar_add() instead of an error.

This reverts 03b59bdb64 ("paramter: The dev_add_param_*() return
ERR_PTR(), change no-ops to return ERR_PTR(-ENOSYS) instead of NULL").
Most callers of dev_add_param_*() don't care about whether
CONFIG_PARAMETER is enabled or not. The remaining ones have already been
prepared for getting a NULL pointer. As a result, these callers will not
fail itself, only because CONFIG_PARAMETER (which is always optional) is
disabled.
