fuse: Apply flags2 only when userspace set the FUSE_INIT_EXT
This is just a safety precaution to avoid checking flags on memory that was
initialized on the user space side. libfuse zeroes struct fuse_init_out
outarg, but this is not guranteed to be done in all implementations.
Better is to act on flags and to only apply flags2 when FUSE_INIT_EXT is
set.
There is a risk with this change, though - it might break existing user
space libraries, which are already using flags2 without setting
FUSE_INIT_EXT.
The corresponding libfuse patch is here
