[PATCH obexd] Fix breaking long lines in vCard's fields

[Rafal Michalski <michalski.raf@gmail.com>]

Previously limit length for vCard's (vCard 2.1 with Quoted Printable
encoding) property line was always set as 75 (QP_LINE_LEN), after
processing each single subfield (for instance under ADR property).
Thus it was not possible to reach limit equal to 0 (then breaking line
is required) for all property subfields.
This patch fixes that issue and length of first line, containing property
parameters, is limited as well.
