[PATCH 4.19 26/55] scsi: be2iscsi: Fix a memleak in beiscsi_init_wrb_handle()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dinghao Liu <dinghao.liu@zju.edu.cn>

[ Upstream commit 235f2b548d7f4ac5931d834f05d3f7f5166a2e72 ]

When an error occurs in the for loop of beiscsi_init_wrb_handle(), we
should free phwi_ctxt->be_wrbq before returning an error code to prevent
potential memleak.
