vfs_gpfs: fix bogus compiler warning

The next commit adds the first call inside Samba to the VFS function
SMB_VFS_FGET_DOS_ATTRIBUTES() and therefor also to
vfs_gpfs_fget_dos_attributes().  No idea why gcc is generating this warning:

[4127/4716] Compiling source3/modules/vfs_aio_fork.c
../../source3/modules/vfs_gpfs.c: In function ‘vfs_gpfs_fget_dos_attributes’:
../../source3/modules/vfs_gpfs.c:1728:2: error: ‘file_id’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 1728 |  update_stat_ex_file_id(&fsp->fsp_name->st, file_id);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated due to -Wfatal-errors.
cc1: all warnings being treated as errors

This change fixes the error.
