Yuezhang Mo f19257997d exfat: zero the reserved fields of file and stream extension dentries
From exFAT specification, the reserved fields should initialize
to zero and should not use for any purpose.

If create a new dentry set in the UNUSED dentries, all fields
had been zeroed when allocating cluster to parent directory.

But if create a new dentry set in the DELETED dentries, the
reserved fields in file and stream extension dentries may be
non-zero. Because only the valid bit of the type field of the
dentry is cleared in exfat_remove_entries(), if the type of
dentry is different from the original(For example, a dentry that
was originally a file name dentry, then set to deleted dentry,
and then set as a file dentry), the reserved fields is non-zero.

So this commit initializes the dentry to 0 before createing file
dentry and stream extension dentry.
