Hangyu Hua b50db15c57 9p/net: fix possible memory leak in p9_check_errors() 
commit ce07087964208eee2ca2f9ee4a98f8b5d9027fe6 upstream.

When p9pdu_readf() is called with "s?d" attribute, it allocates a pointer
that will store a string. But when p9pdu_readf() fails while handling "d"
then this pointer will not be freed in p9_check_errors().

Fixes: 51a87c552dfd ("9p: rework client code to use new protocol support functions")
