Fix warnings: screen.c: screen_puts_len(): Various (4): FP/MI.

Problems   : Assigned value is garbage or undefined @ 5363.
             Result of operation is garbage or undefined @ 5356.
             Result of operation is garbage or undefined @ 5320.
             Result of operation is garbage or undefined @ 5192.
Diagnostic : False positives / Multithreading issues.
Rationale  : Suggested error paths contain incoherent values for
             has_mbyte, enc_utf8, and enc_dbcs, which should always hold
             the relationship has_mbyte = enc_utf8 || enc_dbcs, with
             enc_utf8 and enc_dbcs being mutually exclusive.
             Asserting on the globals, though, fails, because checker
             believes they could be modified by other threads in
             between.
Resolution : Make local copy of globals and assert relationship on them.
