[Feature Request]: Issues found PVS studio static analyzer: aio.cpp

[Seraphimt]

Checklist

• I have searched for a similar issue in this repository and did not find one.

Description

Analyzer message:
V568 Its odd that the argument of sizeof() operator is the sizeof (int) * 512expression. aio.cpp 318 V1086 A call of thememsetfunction will lead to underflow of the bufferid_state`. aio.cpp 318

A highly probable error or very strange code that requires a comment\simplification.

namespace Libraries::Kernel {
#define MAX_QUEUE 512
static s32* id_state;
static s32 id_index;
....
}

void RegisterAio(Core::Loader::SymbolsResolver* sym) {
  id_index = 1;
  id_state = (int*)malloc(sizeof(int) * MAX_QUEUE);
  memset(id_state, 0, sizeof(sizeof(int) * MAX_QUEUE));
  ....
}

sizeof(int) * 512 have type size_t, then sizeof(sizeof(int) * MAX_QUEUE)) == 4 or 8 bytes.
