[PATCH 3/3] fuse: Make file nonseekable if it actually is

[Ross Lagerwall <rosslagerwall gmail com>]

Instead of failing in read() with ENOTSUPP after the lseek on a
nonseekable stream succeeds, make the lseek fail with ESPIPE, as it
should.  This is important for applications which test the return value
of lseek to determine if the file descriptor is seekable.
