[PATCH] doc: Fix malformed table in gadget-testing.rst

[Kohshi Yamaguchi]

The table describing the NCM function attributes in gadget-testing.rst
was malformed, causing Sphinx build warnings. This patch fixes the table
format to align with the reStructuredText specifications.

The border lines of the table were not properly aligned with the column
headers, which was corrected by adjusting the border line lengths to
match the headers.

 The function name to use when creating the function directory is "ncm".
 The NCM function provides these attributes in its function directory:
 
-	===============   ==================================================
-	ifname		  network device interface name associated with this
-			  function instance
-	qmult		  queue length multiplier for high and super speed
-	host_addr	  MAC address of host's end of this
-			  Ethernet over USB link
-	dev_addr	  MAC address of device's end of this
-			  Ethernet over USB link
-	max_segment_size  Segment size required for P2P connections. This
-			  will set MTU to (max_segment_size - 14 bytes)

 and after creating the functions/ncm.<instance name> they contain default
 values: qmult is 5, dev_addr and host_addr are randomly selected.
