[PATCH] 9p: make two arrays static const, makes object smaller

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

Don't populate the arrays on the stack but instead make them
static const. Makes the object code smaller by 386 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  17443	   2076	      0	  19519	   4c3f	fs/9p/vfs_inode_dotl.o

After:
   text	   data	    bss	    dec	    hex	filename
  16897	   2236	      0	  19133	   4abd	fs/9p/vfs_inode_dotl.o

(gcc version 9.2.1, amd64)
