Tharun Balaji 57be03a4c1 fix: guard sceKernelFdatasync against guest socket descriptors ...

Add the guest socket descriptor guard to sceKernelFdatasync before any
native syscall, matching the existing sceKernelFchmod pattern. This
prevents high guest socket descriptors (e.g. 0x10000000) from reaching
the Windows CRT _commit, which would trigger the invalid-parameter
handler, and ensures the correct SCE error is returned on all platforms.

Refactor fdatasync_nid_postfix to delegate to sceKernelFdatasync via
PosixResult, removing the duplicated socket guard and native syscall.

Extend GuestFilesystem tests to cover:
- sceKernelFdatasync on a valid guest socket returns SCE EINVAL (0x80020016)
- sceKernelFdatasync on a closed guest socket returns SCE EBADF (0x80020009)
- sceKernelFdatasync on a high invalid descriptor (0x7fffffff) returns SCE EBADF
- closed-ordinary-descriptor tests now run on Windows (verified _commit on
  a closed descriptor returns EBADF without provoking the CRT handler)
