msm: ipa3: Silently fail on default flt install

ipa3_install_dflt_flt_rules() that installs filtering rules, could
fail when trying to install a default filtering table on a pipe
which is not filtering enabled.
As this function could be called from contexts which are not always
aware of filtering supportability, the function will now silently
fail.
