ntfs3: avoid -Wmaybe-uninitialized warning
This warning shows up with gcc-10 now:
In file included from fs/ntfs3/index.c:15:
fs/ntfs3/index.c: In function 'indx_add_allocate':
fs/ntfs3/ntfs_fs.h:463:9: error: 'bmp_size' may be used uninitialized in this function [-Werror=maybe-uninitialized]
463 | return attr_set_size_ex(ni, type, name, name_len, run, new_size,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
464 | new_valid, keep_prealloc, NULL, false);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fs/ntfs3/index.c:1498:6: note: 'bmp_size' was declared here
1498 | u64 bmp_size, bmp_size_v;
| ^~~~~~~~
The warning does look correct, as the 'out2' label can be reached
without initializing bmp_size and bmp_size_v. Initialize these at
the same place as bmp.
