squash4: Fix an uninitialized variable

Browse source 
gcc says:

grub-core/fs/squash4.c: In function ‘direct_read’:
grub-core/fs/squash4.c:868:10: error: ‘err’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
  868 |       if (err)
      |          ^
cc1: all warnings being treated as errors

This patch initializes it to GRUB_ERR_NONE.
