MIPS: uprobes: remove set but not used variable 'epc'

Browse source 
Fixes gcc '-Wunused-but-set-variable' warning:

arch/mips/kernel/uprobes.c: In function 'arch_uprobe_pre_xol':
arch/mips/kernel/uprobes.c:115:17: warning: variable 'epc' set but not used [-Wunused-but-set-variable]

It's never used since introduction in
commit 40e084a506 ("MIPS: Add uprobes support.")
