pipe: reduce padding in struct pipe_inode_info

mainline inclusion
from mainline-v6.7-rc1
category: performance

This has no effect on 64 bit because there are 10 32-bit integers
surrounding the two bools, but on 32 bit architectures, this reduces
the struct size by 4 bytes by merging the two bools into one word.
