Hangyu Hua b9793c9c03 9p/net: fix possible memory leak in p9_check_errors() 
[ Upstream commit ce07087964 ]

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: 51a87c552d ("9p: rework client code to use new protocol support functions")
