man: ip-macsec: fix gcm-aes-256 formatting issue

The 'ip link add' invocation template at the top of the ip-macsec man
page formats with a pair of extra double quotes:

   ip  link  add  link DEVICE name NAME type macsec [ [ address <lladdr> ]
   port PORT | sci <u64> ]  [  cipher  {  default  |  gcm-aes-128  |  gcm-
   aes-256"}][" icvlen ICVLEN ] [ encrypt { on | off } ] [ send_sci { on |

This is due to missing whitespace around the gcm-aes-256 identifier
in the source file.

Fixes: b16f525323357 ("Add support for configuring MACsec gcm-aes-256 cipher type.")
