Summary
RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()
Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/qedr: Fix potential memory leak in __qedrallocmr()

__qedrallocmr() allocates a memory chunk for "mr->info.pbltable" with initmrinfo(). When rdmaalloctid() and rdmaregistertid() fail, "mr" is released while "mr->info.pbltable" is not released, which will lead to a memory leak.

We should release the "mr->info.pbltable" with qedrfree_pbl() when error occurs to fix the memory leak.
