Subject: RDMA/bnxt_re: Fix an IS_ERR() vs NULL check
Patch-mainline: v6.5-rc1
Git-commit: 4251f631fdfba0b38e4634510c5950ee157cc069
References: jsc#PED-6864
The bnxt_re_mmap_entry_insert() function returns NULL, not error pointers.
Update the check for errors accordingly.
Fixes: 360da60d6c6e ("RDMA/bnxt_re: Enable low latency push")
