isobusfs: add printf format attribute to isobusfs_log()

Browse Source 
All pr_*() log macros use isobusfs_log() which was declared without a
format attribute. Therefore the compiler did not check the format
strings against the provided arguments.

Add __attribute__((format(printf, 2, 3))) to let the compiler detect
mismatching format specifiers.
