wininet: ftp.c Fix crash if input buffer is larger than MAX_PATH

[Phil Lodwick]

The following windows code would crash:

CString root;
CFtpConnection ftp;

ftp->GetCurrentDirectory(root)

as well as:

char root[2048];
DWORD len = 2048;
ftp->GetCurrentDirectory(root, &len);

Because the implementation of FtpGetCurrentDirectoryA was using a buffer off
the stack of size MAX_PATH.  (It eventually calls ZeroMemory on this buffer)

==============================================

ChangeLog:
    Fix crash when calling FtpGetCurrentDirectoryA with a buffer larger than
MAX_PATH
