[Possible enhancement] Redundant check in VirtualMemory.cpp

[sampletext32]

rpcs3/Utilities/VirtualMemory.cpp

Lines 155 to 160 in d451a0b

	while ((m_file = ::shm_open("/rpcs3-mem1", O_RDWR | O_CREAT | O_EXCL, S_IWUSR | S_IRUSR)) == -1)
	{
	if (m_file == -1 && errno == EMFILE)
	{
	fmt::throw_exception("Too many open files. Raise the limit and try again.");
	}

@elad335

Explanation

m_file is already checked for -1 in loop header. So check is redundant inside "if"

Suggestion

	if (errno == EMFILE)

It's a small change and seems correct, you can pull request it yourself as well.
