Subject: [PATCH 27/30] LU-14073 ldiskfs: don't test LDISKFS_IOC_FSSETXATTR

EXT4_IOC_FSSETXATTR was removed upstream in Linux 5.9, Commit
cb29a02d3a9d ("ext4: use generic names for generic ioctls").
So we cannot use it to test if project quotas are supported.

Instead test if EXT4_MAXQUOTAS is 3.  This was changed to 3 upstream
in the commit immediately before EXT4_IOC_FSSETXATTR was added, so it
is effectively the same test.

Test-Parameters: trivial
