[PATCH 11/21] fs: Mark functions as static in jbd2/journal.c

[Rashika Kheria]

Mark functions as static in jbd2/journal.c because they are not used
outside this file.

This eliminates the following warning in jbd2/journal.c:
fs/jbd2/journal.c:125:5: warning: no previous prototype for âjbd2_verify_csum_typeâ [-Wmissing-prototypes]
fs/jbd2/journal.c:146:5: warning: no previous prototype for âjbd2_superblock_csum_verifyâ [-Wmissing-prototypes]
fs/jbd2/journal.c:154:6: warning: no previous prototype for âjbd2_superblock_csum_setâ [-Wmissing-prototypes]
