bcachefs: use nonblocking variant of print_string_as_lines in error path

Browse Source 
The inconsistency error path calls print_string_as_lines, which calls
console_lock, which is a potentially-sleeping function and so can't be
called in an atomic context.

Replace calls to it with the nonblocking variant which is safe to call.
