scsi: hpsa: Replace kmalloc() + copy_from_user() with memdup_user()
Replace kmalloc() followed by copy_from_user() with memdup_user() to
improve and simplify hpsa_passthru_ioctl().
Since memdup_user() already allocates memory, use kzalloc() in the else
branch instead of manually zeroing 'buff' using memset(0).
Return early if an error occurs and remove the 'out_kfree' label.
No functional changes intended.
