sock: annotate data-races around prot->memory_pressure
*prot->memory_pressure is read/writen locklessly, we need
to add proper annotations.
A recent commit added a new race, it is time to audit all accesses.
Fixes: 2d0c88e84e48 ("sock: Fix misuse of sk_under_memory_pressure()")
Fixes: 4d93df0abd50 ("[SCTP]: Rewrite of sctp buffer management code")
