[LU-16796] Replace LASSERT_ATOMIC_* (atomic_t) with reference counters (refcount)

Description

 

For Example.

struct ptlrpc_sec {      
....
atomic_t ps_refcount;    
};

Which is called as...

LASSERT_ATOMIC_ZERO(&sec->ps_refcount);

Now becomes

struct ptlrpc_sec {      
....
struct kref ps_refcount;
};

and every thing should follow to support the above.

 

Currently these are under active use:

LASSERT_ATOMIC_GT
LASSERT_ATOMIC_GT_LT
LASSERT_ATOMIC_ZERO
LASSERT_ATOMIC_POS
