zicflip: fix [ms]ret behavior
Based on Spec chapter 3.5
"An MRET or SRET instruction is used to return from a trap in M-mode or
S-mode, respectively. When executing an xRET instruction, if xPP holds
the value y, then ELP is set to the value of xPELP if yLPE is 1;
otherwise, it is set to NO_LP_EXPECTED; xPELP is set to NO_LP_EXPECTED."
The change follow the last statement after semicolon
"xPELP is set to NO_LP_EXPECTED"
