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

Browse source

__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with
init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr"
is released while "mr->info.pbl_table" is not released, which will lead
to a memory leak.

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

Fixes: e0290cce6a ("qedr: Add support for memory registeration verbs")
