[PATCH 03/12] iscsiuio: Fix invalid parameter when call fstat()

[Wenchao Hao]

Both qedi_open() and bnx2x_open() perform 15 times retry
to make system call open() successful, while this retry
mechanism can not make sure open() can execute successfully.
So this patch verify return value of open(), if it is still
INVALID_FD just print error info and return the errno.
