Even Rouault b3418d2cd6 Fix undefined left shift in ncx_get_size_t() 
Running a build on the .nc file corresponding to the below ncdump output
with -fsanitize=undefined raises

libsrc/ncx.c:4722:26: runtime error: left shift of 255 by 24 places cannot be represented in type 'int'

This is due to *cp being promoted to int before doing the left shift, instead
of the intended unsigned. So do the cast to unsigned internally rather than
externally

ncdump file to reproduce:

netcdf temp {
dimensions:
	y = UNLIMITED ; // (0 currently)
	x = 109067 ;
variables:
	byte t(y, x, x) ;
data:
}
