kernel.h: Silence sparse warning in lower_32_bits
I keep getting sparse warnings in crypto such as:
CHECK drivers/crypto/ccree/cc_hash.c
drivers/crypto/ccree/cc_hash.c:49:9: warning: cast truncates bits from constant value (47b5481dbefa4fa4 becomes befa4fa4)
drivers/crypto/ccree/cc_hash.c:49:26: warning: cast truncates bits from constant value (db0c2e0d64f98fa7 becomes 64f98fa7)
[.. many more ..]
This patch removes the warning by adding a mask to keep sparse
happy.
