microblaze: kgdb: Remove unused variable and fix return value
I forget to remove unused variable from kgdb_arch_handle_exception. Fix return value in microblaze_kgdb_break function. Error log: arch/microblaze/kernel/kgdb.c: In function 'microblaze_kgdb_break': arch/microblaze/kernel/kgdb.c:83: warning: 'return' with a value, in function returning void arch/microblaze/kernel/kgdb.c: In function 'kgdb_arch_handle_exception': arch/microblaze/kernel/kgdb.c:119: warning: unused variable 'cpu' Signed-off-by: Michal Simek <monstr@monstr.eu>
