xfs: fix uninit warning in xfs_growfs_data
Quiet down this gcc warning:
fs/xfs/xfs_fsops.c: In function ‘xfs_growfs_data’:
fs/xfs/xfs_fsops.c:219:21: error: ‘lastag_extended’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
219 | if (lastag_extended) {
| ^~~~~~~~~~~~~~~
fs/xfs/xfs_fsops.c:100:33: note: ‘lastag_extended’ was declared here
100 | bool lastag_extended;
| ^~~~~~~~~~~~~~~
By setting its value explicitly. From code analysis I don't think this
is a real problem, but I have better things to do than analyse this
closely.
