[PATCH v3 1/2] fsck.c: modify fsck_ident() and fsck_commit()

[Ashwin Jha <ajha.dev@gmail.com>]

In fsck_ident(): Replace argument char **ident with const char **ident
In fsck_commit(): Replace char *buffer with const char *buffer

In both the cases, referenced memory addresses are not modified. So, it
will be a good practice, to declare them as const.

Eric (follow at [1]).
