[PATCH v2] octeontx2-pf: mcs: Remove dead code and semi-colon from rsrc_name()

[Nihar Chaithanya]

Every case in the switch-block ends with return statement, and the 
default: branch handles the cases where rsrc_type is invalid and 
returns "Unknown", this makes the return statement at the end of the 
function unreachable and redundant.
The semi-colon is not required after the switch-block's curly braces.

Remove the semi-colon after the switch-block's curly braces and the 
return statement at the end of the function.

This issue was reported by Coverity Scan.
Report:
CID 1516236: (#1 of 1): Structurally dead code (UNREACHABLE)
unreachable: This code cannot be reached: return "Unknown";.
