[disco:linux PATCH 1/1] Revert "RDMA/cm: Fix memory leak in cm_add/remove_one"

[Marcelo Henrique Cerri]

BugLink: https://bugs.launchpad.net/bugs/1859582

This reverts commit f56d075cabc10ddbcfc1bf2c8291c46995176a86.

cm_remove_port_fs() in 5.0 doesn't behave as in upstream and the
additional kfree(port) is not necessary.
