[Mellanox] fix hw-mgmt patches (#9539)

- Why I did it
To fix an issue that hw-mgmt patches were not applied. One patch was already in upstream hw-mgmt package thus applying it again caused an error and no other patches were applied. Also, I did it to improve the Makefile, so that the make will fail in case patches fail to apply.

- How I did it
Removed obsolete patch, made applying patches a hard failure in the build.

- How to verify it
Run the make and verify patches are applied.
