logfs: fix build warning
fs/logfs/dev_bdev.c: In function '__bdev_writeseg': include/linux/kernel.h:601:17: warning: comparison of distinct pointer types lacks a cast [enabled by default] (void) (&_min1 == &_min2); \ fs/logfs/dev_bdev.c:84:14: note: in expansion of macro 'min' max_pages = min(nr_pages, BIO_MAX_PAGES); fs/logfs/dev_bdev.c: In function 'do_erase': include/linux/kernel.h:601:17: warning: comparison of distinct pointer types lacks a cast [enabled by default] (void) (&_min1 == &_min2); \ fs/logfs/dev_bdev.c:174:14: note: in expansion of macro 'min' max_pages = min(nr_pages, BIO_MAX_PAGES); Lets use min_t and mention the type.
