  lib-storage: Prevent recursion in header parsing

If header parsing error occurs and error handling tries
to get fields, such as Message-ID, it will cause
crash. This fixes problem by preventing reading from
non-cached headers while they are being parsed.

Fixes lmtp: Panic: file ../../../src/lib/array.h: line 219 (array_idx_i):
assertion failed: (idx * array->element_size < array->buffer->used)
