tree-wide: Handle EINVAL as not supported for chattr_xxx()

F2FS returns EINVAL from FS_IOC_SETFLAGS when trying to set
FS_NOCOW_FL. Let's handle this by treating EINVAL as not supported.
While we're at it, make sure we use ERRNO_IS_IOCTL_NOT_SUPPORTED()
across the tree instead of ERRNO_IS_NOT_SUPPORTED() when calling any
of the chattr_xxx() functions.

Fixes #37593
