file-posix: Fix EINTR handling
EINTR should be checked against errno, not ret. While fixing the bug,
collect the branches with a switch block.
Also, change the return value from -ENOSTUP to -ENOSPC when the actual
issue is request range passes EOF, which should be distinguishable from
the case of error == ENOSYS by the caller, so that it could still retry
with other byte ranges, whereas it shouldn't retry anymore upon ENOSYS.
