drivers/mtd: fix mtd_write_sector

[gschorcht]

Contribution description

This PR fixes mtd_write_sector function introduced with PR #20180.

mtd_write_page_raw requires the number of bytes to be written as parameter, which is the number of sectors to be written (parameter count) multiplied by the pages per sector mtd->pages_per_sector and the page size mtd->page_size.

Testing procedure

Use any board with SPI SD Card interface and set ENABLE_DEBUG in drivers/mtd_sdcard.c. Without the PR, writing to the SD card fails because of the wrong size. Formatting the SD card doesn't hangs.

> vfs w /sd0/test1.txt ascii o hello
mtd_sdcard_read_page: page:1991 offset:0 size:512
mtd_sdcard_write_page: page:1991 offset:0 size:1019392
mtd_sdcard_write_page: error 4
Write error: -EIO
mtd_sdcard_write_page: page:1991 offset:0 size:1019392
mtd_sdcard_write_page: error 3

With the PR writing to the SD card and formatting it works as expected.

> vfs w /sd0/test1.txt ascii o hello
mtd_sdcard_read_page: page:1991 offset:0 size:512
mtd_sdcard_read_page: page:95 offset:0 size:512
mtd_sdcard_write_page: page:95 offset:0 size:512
mtd_sdcard_write_page: page:2055 offset:0 size:512
mtd_sdcard_read_page: page:1991 offset:0 size:512
mtd_sdcard_write_page: page:1991 offset:0 size:512
mtd_sdcard_write_page: page:64 offset:0 size:512
