Remove unused label

Remove unused label

Wunused-label is a stupid gcc option as removing the
warnings it produces often makes the code harder to
read. But such is life ....

fs/pstore/ram.c:633:1: warning: label 'fail_init_fprz'
defined but not used [-Wunused-label]
fs/pstore/ram.c:629:1: warning: label 'fail_init_mprz'
defined but not used [-Wunused-label]
