fs/ntfs3: fix mount failure on 64K page-size kernels

On 64K page-size kernels, mounting NTFS volumes smaller than ~650 MB
fails with EINVAL. The issue is in log_replay(): the initial log page
size probe uses PAGE_SIZE (65536) instead of DefaultLogPageSize (4096)
when PAGE_SIZE exceeds DefaultLogPageSize * 2.

This makes norm_file_page() require the $LogFile to be at least
50 * 65536 = 3.2 MB, but mkfs.ntfs creates a $LogFile of only ~1.5 MB
for a typical 300 MB volume. norm_file_page() returns 0 and the mount
is rejected with EINVAL.

On 4K kernels the #if guard evaluates to true, so use_default=true is
passed and DefaultLogPageSize (4096) is used, requiring only ~200 KB.
This path works fine.

Fix this by always passing use_default=true, which forces the initial
probe to use DefaultLogPageSize regardless of the kernel's PAGE_SIZE.
This is safe because, after reading the on-disk restart area, log_replay()
already re-adjusts log->page_size to match the volume's actual
sys_page_size.

Also fix read_log_page() to pass log->page_size instead of PAGE_SIZE to
ntfs_fix_post_read(), matching the actual buffer size.
