[PATCH] spi: sophgo: fix incorrect type for ret in sg2044_spifmc_write()

[Qasim Ijaz <qasdev00@gmail.com>]

The sg2044_spifmc_write() function uses 'ret' of unsigned type 
size_t to capture return values from sg2044_spifmc_wait_xfer_size() 
and sg2044_spifmc_wait_int(). Since these functions may return 
negative error codes, using an unsigned type prevents proper 
error detection, as size_t cannot represent negative values. 

Change 'ret' to type int so that negative values are handled correctly.
