s390/dumpstack: use pr_cont where appropriate
Use pr_cont instead of simple printk calls when lines will be continued. This fixes the kernel output of various lines printed on e.g. a warning: Before: [ 0.840604] Krnl PSW : 0404c00180000000 000000000017d1d2 [ 0.840606] (try_to_wake_up+0x382/0x5e0) [ 0.840610] R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:3 CC:0 PM:0 [ 0.840611] RI:0 EA:3 After: [ 0.831772] Krnl PSW : 0404c00180000000 000000000017d14a (try_to_wake_up+0x382/0x5e0) [ 0.831776] R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:3 CC:0 PM:0 RI:0 EA:3 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
