fs/jfs/super.c: convert simple_str to kstr

Browse Source 
This patch replaces obsolete simple_str functions by kstr

use kstrtouint for
-uid_t ( __kernel_uid32_t )
-gid_t ( __kernel_gid32_t )
-jfs_sb_info->umask
-jfs_sb_info->minblks_trim
(all unsigned int)

newLVSize is s64 -> use kstrtol

Current parse_options behaviour stays the same ie it doesn't return kstr
rc but just 0 if function failed (parse_options callsites
return -EINVAL when there's anything wrong).
