RDMA/bnxt_re: Fix to drop reference to the mmap entry in case of error

Browse source

[ Upstream commit c84f0f4f49 ]

In the error handling path of bnxt_re_mmap(), driver should invoke
rdma_user_mmap_entry_put() to free the reference of mmap entry in case
the error happens after rdma_user_mmap_entry_get was called.
