Subject: [RFT net] net: ipa: fix u32_replace_bits by u32p_xxx version

Looks like u32p_replace_bits() should be used instead of
u32_replace_bits() which does not modifies the value but returns the
modified version.

Fixes: 2b9feef2b6c2 ("soc: qcom: ipa: filter and routing tables")

Found it while grepping of u32_replace_bits() usage and
replaced it w/o testing.
