Fix crash in refactored lexer internals

Commit f0e67a1d29102aa9905aecf2b0f98449697d5af3 changed the control
flow so that PerlIO_tell(PL_rsfp) could be called when PL_rsfp was
NULL, which produces a crash at least on Windows with the MSVCRT
runtime.

This change moves the detection if PL_rsfp is NULL or not closer to
the location where is is actually tested, which gets rid of the
crashes.  I however have *not* verified if the changes in control
flow in f0e67a1d are otherwise correct or not.
