[ Upstream commit 698a82ebfb4b2f2014baf31b7324b328a2a6366e ]
This patch fixes the static code analyzer reported issues
in rvu_npc.c. The reported errors are different sizes of
operands in bitops and returning uninitialized values.
Fixes: 651cd2652339 ("octeontx2-af: MCAM entry installation support")
