RDMA/rtrs: Fix use-after-free in path file creation cleanup (2026-05-19 19:32:48 -0300)

----------------------------------------------------------------
RDMA v7.1 first rc window

- syzbot triggred crash in rxe due to concurrent plug/unplug

- Possible non-zero'd memory exposed to userspace in bnxt_re

- Malicous 'magic packet' with SIW causes a buffer overflow

- Tighten the new uAPI validation code to not crash in debugging prints and have the right module dependencies in drivers

- mana was missing the max_msg_sz report to userspace

- UAF in rtrs on an error path
