[LTP] [PATCH v2 2/2] syscalls/quotactl04.c: Specify inode size for prjquota feature

[Xiao Yang]

Background:
1) LTP uses default 256M filesystem to run test.
2) Mke2fs sets inode size to 128 bytes for small filesystem(e.g. 256M) usually.
3) Prjquota feature requires bigger inode size which is at least 256 bytes.

New mke2fs can adjust inode size to 256 bytes automatically by commit 66aae96
in e2fsprogs, but old mke2fs cannot do it and reports the following error:
-----------------------------------------------------------
mke2fs 1.43.4 (31-Jan-2017)
mkfs.ext4: 128 byte inodes are too small for project quota; specify larger size
-----------------------------------------------------------

Make quotactl04 with old mke2fs work by specifying inode size to 256 bytes.
