r300620:

Use reallocf instead of malloc to fix leak with outbuf_pmap

The previous code overwrote outbuf_pmap's memory with malloc once per
loop iteration, which leaked its memory; use reallocf instead to ensure
that memory is properly free'd each loop iteration.

Add a outbuf_pmap = NULL in the failure case to avoid a double-free
at the bottom of the function.

CID: 1038776

r300621:

Remove redundant NULLing of outbuf_pmap

If reallocf ever failed, outbuf_pmap would already be NULL

MFC r290253:

Remove unnecessary `if (x)` tests before calling `free(x)`; free(3)
already employs this check
