INT 2F - NETWORK REDIRECTOR - FIND FIRST FILE WITHOUT CDS

	AX = 1119h
	SS = DS = DOS DS
	[DTA] = uninitialized 21-byte findfirst search data
	      (see #01626 at INT 21/AH=4Eh)
	SDA first filename pointer -> fully-qualified search template
	SDA search attribute = attribute mask for search
Return: CF set on error
	    AX = DOS error code (see #01680 at INT 21/AH=59h/BX=0000h)
	CF clear if successful
	    [DTA] = updated findfirst search data
		    (bit 7 of first byte must be set)
	    [DTA+15h] = standard directory entry for file (see #01352)
Notes:	this function is called by the DOS 3.1+ kernel
	DOS 4.x IFSFUNC returns CF set, AX=0003h
