e2fsprogs: Use 32-bit variant of ext2fs_swab to read i_projid

i_projid is a 32-bit field of the inode. Hence this commit uses
ext2fs_swab32() to convert the i_projid field from the on-disk little
endian format to the host cpu format. Without this change, project quota
consistency check used to fail on big endian powerpc systems.
