Juergen-Fahlbusch aa647a9ea5 AP_FlashStorage: set current_sector during init 
Corrects internal error 0x200000 and issue where parameters could not be saved permanently

Analysis revealed that:
Sector 0 was marked with status [SECTOR_STATE_AVAILABLE]
Sector 1 was marked with status [SECTOR_STATE_IN_USE]
Consequently, the current parameters were being loaded from Sector 1.

neo-0007 fa6335ec47 AP_FlashStorage: remove unset macro & skip multiwrite check for F4/F7 
AP_FLASHSTORAGE_MULTI_WRITE is not defined anywhere so the FlashStorage
test with multiwrite will always fail even for F4,F7 (linux builds also) which support
multwrite.

fix some comments about flash type count and typo in STM32F4 and STM32F7 names

Fixes #14168

Andrew Tridgell 6e1e89bb70 AP_FlashStorage: fixed a corruption bug 
many thanks to @sh83 for tracking down this bug. When write_all() is
called with non-zero offset in init it ends up calling write with an
invalid offset, triggering a full reset

This fixes issue #10874

Andrew Tridgell 1513246040 AP_FlashStorage: fixed two bugs found by night-ghost 
this fixes two issues found by night-ghost. The first occurs if a 16
bit flash write is not atomic and only the first byte is written. Then
we could end up declaring the data invalid on reboot and erasing.

The second is a race in switching sectors. If power off occurs at the
wrong time we would trigger en erase on reboot.
