[BUG] Issues on NXFFS

### Description / Steps to reproduce the issue

Hello all!

I would like to report some issues with the NuttX wear-leveling FLASH file system (NXFFS). I'll try and be very brief on the description and how to replicate.

The `fstest` program fails on the first iteration after creating and deleting a file from the mount point.

On the Espressif CI, we test SPI Flash in all devices available on NuttX using four different file systems: `smartfs`, `littlefs`, `spiffs` and `nxffs`.
The test only fails for `nxffs` and it happens on all devices.

On this example, I cleared the flash and uploaded the test binary.
The test creates a file on `/data`, then deletes it and runs `fstest`. You can see that it fails to open files for writing.

```
---- boot ----
nsh> mount
/data type nxffs
/proc type procfs
nsh> echo "Espressif" > /data/esp.txt
nsh> cat /data/esp.txt
Espressif
nsh> rm /data/esp.txt
nsh> fstest -n 2 -o 10 -m /data

To reproduce this binary on ESP32-S3 (its similar for other devices):
- ./tools/configure.sh esp32s3-devkit:spiflash
- Enable NXFFS on board bringup and FSTEST:
```
CONFIG_ARCH_BOARD_COMMON=y
CONFIG_DEBUG_FEATURES=y
CONFIG_DEBUG_ASSERTIONS=y
CONFIG_DEBUG_ASSERTIONS_EXPRESSION=y
CONFIG_DEBUG_SYMBOLS=y
CONFIG_ESP32S3_MERGE_BINS=y
CONFIG_ESP32S3_SPIFLASH_NXFFS=y
CONFIG_ESP32S3_SPIFLASH_SMARTFS=n
CONFIG_ESP32S3_SPI_FLASH_DONT_USE_ROM_CODE=y
CONFIG_NDEBUG=n
CONFIG_TESTING_FSTEST=y
CONFIG_TESTING_FSTEST_STACKSIZE=8192
```

I would appreciate if anyone could assist on debugging this issue, if possible even on a different board.

Thanks all,
Filipe
