mdocml: Since the mdoc/man parser unification, the parser is always

[schwarze]

Log Message:
-----------
Since the mdoc/man parser unification, the parser is always allocated
in mparse_alloc(), so delete all the curp->man == NULL checks.
Triggered by a patch from Christos Zoulas suggesting to add 
yet another such check.
