[ Upstream commitc44000b653] The imc perf fd close() calls are missing from all error paths. In addition, get_mem_bw_imc() handles fds in a for loop but close() is based on two fixed indexes READ and WRITE. Open code inner for loops to READ+WRITE entries for clarity and add a function to close() IMC fds properly in all cases.
