lpm: uninline some functions

Browse Source 
Tests showed that the function inlining caused performance drop
on some x86 platforms with the memory ordering patches applied.
By force no-inline functions, the performance was better than
before on x86 and no impact to arm64 platforms.

Besides inlines of other functions are removed to let compiler
to decide whether to inline.
